American Life Explained: The 10 Everyday Habits That Most Surprise International Visitors to the US

Foreign visitors often arrive in the United States expecting familiar travel experiences, only to encounter everyday customs that feel surprisingly different. New research analysing Reddit discussions has identified the biggest American culture shocks, ranging from casual small talk and huge restaurant portions to tipping, car dependence, visible poverty and prescription drug advertising.

The study, published by digital entertainment platform BC Game in August 2026, examined conversations on Reddit to identify the everyday aspects of American life that most frequently surprise international visitors.

The research grouped recurring experiences into common themes and ranked them according to the number of Reddit comments mentioning each subject. Google media interest was then used as an additional indicator of how widely individual aspects of American culture are discussed internationally.

With international tourism to the United States expected to remain substantial, the findings offer an insight into the less obvious differences travellers can encounter once they move beyond traditional attractions.

Why does American friendliness surprise foreign visitors?

Surprisingly friendly strangers ranked as the biggest culture shock, with 216 Reddit comments and 221 million media mentions.

For many international visitors, particularly those from cultures where conversations with strangers are more reserved, American small talk can feel unusually direct and frequent.

Travellers commonly describe being asked how they are doing by shop assistants, colleagues, hotel staff and complete strangers, even when no detailed response is expected. The phrase often functions more as a greeting than a genuine invitation to discuss someone’s wellbeing.

This distinction can initially confuse visitors who interpret the question literally. What feels like an invitation to have a conversation may simply be a conventional form of social politeness in many parts of the US.

The contrast illustrates how apparently simple interactions can become significant cultural differences for international travellers.

Why are American restaurant portions so large?

Supersized food portions ranked second, with 198 Reddit comments and 184 million media mentions.

Large restaurant servings are another recurring surprise for foreign visitors. Travellers frequently report ordering what they believe is an ordinary meal and receiving considerably more food than expected.

Some Reddit discussions suggest that a single restaurant order can be enough for two or even three meals, depending on the dish and the traveler’s appetite.

For visitors accustomed to smaller portions, the experience can affect everything from dining budgets to food waste and meal planning. It also helps explain why takeaway boxes and leftovers are such a familiar part of the American restaurant experience.

Portion sizes are not uniform across the country or every type of restaurant, but the perception of American meals being particularly generous remains widespread among international visitors.

Why does tipping confuse international tourists?

Tipping culture ranked third, with 192 Reddit comments and 291 million media mentions.

Few aspects of American dining generate as much uncertainty for foreign visitors as tipping.

In many countries, service charges are incorporated into prices or restaurant bills, meaning customers do not have to calculate an additional gratuity after receiving service. In the United States, however, tipping remains an established part of many service interactions.

Visitors can therefore find themselves wondering how much to leave, when to tip and whether tipping is expected in a particular situation.

The research even highlighted an example of a foreign visitor attempting to tip a McDonald’s cashier, illustrating how unfamiliar the boundaries of American tipping can appear to someone encountering the system for the first time.

The sheer volume of international discussion surrounding the subject reinforces how distinctive the practice appears to many visitors.

Why do tourists find American cities so car dependent?

Car dependence, poor walkability and limited public transport generated 119 Reddit comments and 94.7 million media mentions.

Visitors from Europe and parts of Asia can be particularly surprised by the scale of American car dependence.

While major metropolitan areas such as New York, Washington DC, Chicago and San Francisco have extensive public transport networks, mobility can be considerably more difficult in many smaller cities and suburban areas.

International travellers may discover that attractions, restaurants, hotels and shopping areas are separated by distances that are inconvenient or impractical to walk. Public transport may also be limited outside major urban centres.

For tourists accustomed to compact cities and frequent rail, tram or bus services, the need to use a car, taxi or rideshare service can significantly change the economics and logistics of a US holiday.

Why does visible homelessness shock foreign travellers?

Homelessness and visible poverty ranked fifth, generating 117 Reddit comments and 14.7 million media mentions.

Visible homelessness is another issue that frequently catches international visitors off guard.

San Francisco and Los Angeles are repeatedly mentioned in online discussions, particularly in relation to tents, people sleeping outdoors and homelessness around central urban areas and transport locations.

The contrast can be especially striking for tourists because these scenes appear alongside some of the world’s most affluent neighbourhoods, technology companies, hotels, restaurants and tourist attractions.

The issue is complex and varies significantly between cities and neighbourhoods. Nevertheless, its visibility means that it can become an unexpected part of the experience for visitors exploring major American destinations.

Why do prescription drug adverts surprise foreign visitors?

Prescription drug commercials ranked sixth, with 114 Reddit comments and 15.4 million media mentions.

Television advertising for prescription medicines is another feature that can appear unusual to international travellers.

Visitors from countries where direct-to-consumer advertising of prescription medicines is restricted may be surprised to see television commercials promoting specific treatments and encouraging viewers to speak to their doctors.

The advertisements can become particularly memorable because they often combine lifestyle-focused messaging with long lists of potential side effects and medical warnings.

For tourists, this is an example of how differences in healthcare systems and advertising regulations can become visible through ordinary television viewing.

Why does American gun culture surprise foreign visitors?

Guns and visible armed security generated 111 Reddit comments and 55 million media mentions.

American gun culture also features prominently among the experiences discussed by foreign visitors.

Travellers from countries with tighter restrictions on civilian firearm ownership may find the presence of guns, armed security personnel or firearm-related businesses unfamiliar.

The experience differs considerably by state, city and setting, so it should not be treated as representative of every American destination. However, the subject remains one of the more recognisable cultural differences identified by international visitors.

For tourists, the surprise often comes from encountering a part of American society that is less visible in their home countries.

Why do American flags and patriotism stand out to tourists?

Flags, patriotism and the Pledge of Allegiance attracted 102 Reddit comments and 81.8 million media mentions.

The prominence of American flags and displays of national identity can also attract attention from foreign visitors.

Travellers may encounter flags on homes, public buildings, businesses and vehicles, while schools and civic settings can involve traditions that are unfamiliar elsewhere.

The Pledge of Allegiance is particularly notable to visitors who did not grow up with an equivalent daily school ritual.

These practices can provide international travellers with a different perspective on how national identity is expressed in everyday American life.

Why do visitors notice sweet and processed American food?

Overly sweet and processed food ranked ninth, with 99 Reddit comments and 38.3 million media mentions.

Food is another major source of cultural contrast.

Foreign travellers frequently comment on the sweetness of products, the availability of processed foods and differences in recipes compared with what they are accustomed to eating at home.

The experience can extend beyond desserts to breakfast cereals, sauces, breads, drinks and packaged snacks.

While the American food scene is exceptionally diverse and includes cuisines from around the world, visitors may still notice different levels of sweetness, portioning and processing in mainstream products.

Why are taxes added at the checkout?

Hidden taxes at checkout generated 87 Reddit comments, although the study recorded only 1.3 million media mentions.

One of the smaller culture shocks identified by the study concerns sales tax.

Foreign visitors may see one price displayed on a shelf or menu and discover that the final amount is higher when they reach the checkout.

This can be confusing for travellers accustomed to systems where consumer prices generally include the tax payable at the point of purchase.

The difference is particularly noticeable when tourists are managing a fixed travel budget, because the advertised price does not always represent the final amount they will pay.

What other American habits surprise foreign visitors?

BC Game also highlighted several additional observations from its research.

Electric kettles were identified as an unexpected difference for some visitors, particularly travellers from countries where kettles are a common household appliance for preparing tea or instant coffee.

Religious life was another recurring theme. Some foreign visitors reported being surprised by the visibility of churches and the extent to which religion can enter everyday conversations in some American communities.

These experiences underline a broader point about international travel: culture shock is not necessarily created by major political or social differences. It can come from seemingly ordinary routines that local residents barely notice.

What does the research mean for travellers visiting the US?

The findings provide a useful reminder that travelling to the United States involves more than navigating airports, attractions and accommodation.

Understanding local conventions can make the experience easier, particularly for first-time visitors. Travellers can prepare by researching tipping expectations, checking whether local transport is practical, allowing for sales tax when budgeting and understanding that casual American greetings may not require a detailed answer.

At the same time, the study should be viewed as an analysis of online discussions rather than a scientific measurement of every foreign visitor’s experience. Reddit users represent a particular online audience, while cultural expectations vary according to nationality, age, travel experience and destination.

The research is therefore most useful as a snapshot of recurring perceptions rather than a definitive description of every American city or traveller.

The research shows that America’s biggest culture shocks often involve ordinary routines rather than famous attractions. Small talk, large meals, tipping, driving, visible homelessness and checkout taxes can all surprise international visitors. Understanding these differences before departure can help travellers budget realistically, navigate local customs and approach unfamiliar experiences with greater confidence.
