Things That Surprise Americans Most on Their First International Trip

In the US, tipping 18–20% at restaurants is standard practice and forms a meaningful part of service workers' income. Abroad, the calculus is completely different. In Japan, tipping is widely considered rude and can cause genuine awkwardness. In much of Europe, rounding up a bill or leaving small change is appreciated but a 20% tip would raise eyebrows. In Australia, tipping is optional and uncommon. Before each trip, it's worth quickly researching local customs — you'll avoid over- or under-tipping and signal cultural awareness.

The US runs on 110–120 volts with Type A/B plugs. Most of the world uses 220–240 volts with entirely different plug shapes. Plugging a US device into a foreign outlet without the right adapter — or a dual-voltage converter if the device requires it — can damage electronics or create a safety hazard. Most modern laptops and phone chargers are dual-voltage (check the fine print on the charger itself), but hair dryers, curling irons, and some appliances often are not. A universal travel adapter is a small investment that prevents real headaches.

Americans are accustomed to grabbing common medications — antihistamines, cold medicine, certain pain relievers — off a drugstore shelf. In many countries, what's over-the-counter in the US requires a prescription, and pharmacists play a much more active clinical role. Conversely, some medications that require a prescription in the US are available over the counter elsewhere. If you rely on specific medications, bring an adequate supply from home.

In the US, a restaurant meal often moves at a brisk pace — servers check in frequently, refills arrive automatically, and the check appears promptly. In much of Europe and Latin America, a meal is a leisurely social event. Your server won't rush you, free refills aren't a given, and requesting the check is your job, not theirs. Portion sizes also tend to be smaller and more calibrated. Neither approach is wrong — but resisting the urge to interpret a slower pace as poor service makes the whole experience more enjoyable.

Asking for "water" at a restaurant in many European countries will get you a bottle — and a charge on your bill. Still or sparkling will be a follow-up question, and free tap water isn't automatically offered the way it is at most US restaurants. In some destinations, tap water is perfectly safe to drink; in others it isn't. This is worth researching per destination rather than assuming either way. Our piece on international travel myths addresses the "tap water is always unsafe" assumption directly.

American service culture is famously warm and performatively friendly — cashiers greet you enthusiastically, retail staff offer help immediately, and smiling is ubiquitous. In many other countries, professional service is more reserved. A French shopkeeper who doesn't greet you effusively isn't being rude; that's simply how professional interaction is calibrated there. Adjusting your expectations — and often initiating a greeting yourself in the local language — goes a long way toward making interactions feel warmer and more mutual.

Many US bank and credit cards charge a foreign transaction fee — typically 1–3% — on every purchase made abroad. Airport and hotel currency exchange kiosks often offer unfavorable rates compared to local ATMs or fee-free cards. These costs accumulate faster than most travelers expect. Before you leave, check whether your card charges foreign transaction fees, and understand how currency conversion actually works. Our dedicated article on foreign transaction fees breaks this down in practical detail.
