Some parts of daily life feel universal, but others are tied closely to culture, and that’s where the U.S. and the U.K. often surprise each other. From casual habits to big traditions, there are plenty of things that feel completely normal in America yet barely exist across the Atlantic. That’s the focus of these 10 uniquely American things you won’t see happening in the U.K., a look at quirks that stand out the moment you cross borders.
These differences aren’t just small curiosities, they show how culture shapes everyday life in ways travelers instantly notice. From free drink refills to oversized vehicles, the contrasts can be funny, confusing, or just plain surprising. Curious what makes the list? Take a look and see which of these American habits would raise eyebrows, or at least a few questions, in the U.K.
Free Refills Everywhere
In the U.S., walking into a diner or fast-food restaurant almost guarantees that your drink will be topped off without a second thought. Soda fountains let customers refill cups as many times as they want, and servers at sit-down restaurants will bring another coffee or iced tea before you’ve finished the first. This casual approach to unlimited refills is practically unheard of in the U.K., where drinks are usually served in single portions and a refill—if available—often comes at an extra cost. For Brits, the concept of endless soda or coffee feels foreign, and it’s a clear cultural difference.
Tipping 20% as a Rule
In America, tipping 20% is practically automatic at restaurants, bars, and even for services like haircuts or taxis. It’s considered part of the cost of the meal or experience, and failing to tip generously is often seen as rude. In the U.K., tipping is far less dramatic—most restaurants add a service charge or expect only a small tip for good service. Leaving 20% would feel unusual and overly generous to most British staff. This difference reflects not just dining habits, but also contrasting systems of wages and expectations around service, which locals notice immediately when Americans visit.
Flying Huge Flags on Homes
In the U.S., it’s common to see large American flags flying outside houses, lining suburban streets, or even hanging from porches year-round. Many homeowners proudly display them, especially around holidays like the Fourth of July or Memorial Day. In the U.K., flag-flying at home is far less common, and large displays are often reserved for official events or special occasions. Brits might see daily flag displays as overly patriotic or unusual, while for Americans, it’s simply a way of showing pride and identity. This habit is instantly recognizable as a cultural marker for anyone visiting from across the Atlantic.
Drive-Thru Everything
America is famous for its drive-thru culture—not just for burgers and coffee, but for banks, pharmacies, even dry cleaners. People rarely have to leave their cars for basic errands, and whole strips of businesses are designed for quick, window-to-window service. In the U.K., drive-thrus exist but are limited mostly to fast food, and the idea of handling your banking or prescription pickup from the car window feels strange. The U.S. love of convenience and speed plays out visibly in this habit, and for British visitors, the number of drive-thru lanes can be surprising.
School Sports as Major Events
In the U.S., high school football games can fill stadiums, with marching bands, cheerleaders, and entire towns showing up to watch. These games often feel like community events, drawing big crowds and even media coverage. Students and alumni wear school colors proudly, and Friday nights under stadium lights are a staple in many towns. In the U.K., school sports don’t carry the same public spectacle; games are more low-key and rarely become town-wide gatherings. The scale and enthusiasm Americans bring to high school sports can seem outsized to Brits, but it’s a deeply rooted part of many U.S. communities.
Massive Food Portions

American restaurants are known for their large serving sizes, often giving customers more food than they can realistically eat in one sitting. Meals are frequently served on oversized plates piled high with multiple side dishes, creating a filling experience that many locals expect. In contrast, portion sizes in the U.K. tend to be smaller and more restrained, reflecting a different approach to dining and food culture. Visitors from America may be surprised by the lighter servings, which focus on quality over quantity. This difference in portion size is a clear and common marker of cultural variation between the two countries.
Sales Tax Added at Checkout
In the U.S., prices on store shelves and menus usually don’t include sales tax, so the final amount you pay is often higher than what you see advertised. This means customers must mentally calculate the extra percentage added at checkout or when the bill arrives. In the U.K., on the other hand, all prices include value-added tax (VAT), so the price you see is the price you pay. This system eliminates surprise costs at the register and simplifies shopping. Americans visiting the U.K. often find this inclusive pricing more straightforward, while Brits may find the U.S. system confusing or misleading.
Tailgating Before Games
Tailgating is a uniquely American tradition where fans gather in parking lots before sporting events to grill food, play games, and socialize. This festive pre-game ritual creates a sense of community and excitement hours before kickoff. The U.K. doesn’t have a comparable practice; instead, fans typically arrive shortly before the event without the elaborate outdoor parties. Tailgating’s popularity in the U.S. spans football, baseball, and other sports, and it often involves large groups with coolers, tents, and music. For British visitors, the scale and enthusiasm of American tailgates can be surprising and distinctly different from their own sporting culture.
Prescription Drug Ads on TV
In the U.S., television commercials frequently advertise prescription medications, encouraging viewers to ask their doctors about specific drugs. These ads are a common part of American TV and are aimed at educating and influencing consumer behavior directly. In the U.K., this kind of advertising is banned; prescription medications are promoted through healthcare providers rather than public media. This difference reflects varying regulations and cultural attitudes toward pharmaceutical marketing. British visitors watching American television often find the constant drug ads unusual or intrusive, highlighting a clear contrast in how health products are presented.
Red Solo Cups at Parties
The red plastic Solo cup has become an iconic symbol of American parties, often seen at college gatherings, barbecues, and casual get-togethers. These disposable cups are valued for their convenience and durability, making them popular for serving drinks in informal settings. In the U.K., such cups are far less common; parties typically use reusable glassware or different types of disposable cups. The red Solo cup’s association with American culture is strong enough that it’s frequently referenced in movies, music, and media. For visitors, spotting these cups is an immediate visual cue of an American-style party atmosphere.
