Order jerk chicken at a Jamaican spot and the server might open with a blunt "Wha yuh want?" No smile, no small talk, no checking in on your table every five minutes. For first-time visitors from the US, that can read as rude — but in much of the Caribbean, it just means the food is about to be excellent. A round-up of discussions among travellers highlights five habits Americans routinely get wrong within minutes of sitting down.

First, service culture. Many small Caribbean kitchens put flavour above hospitality theatre. Meals are social occasions, not transactions, and terse answers are normal. Aruba has a reputation for warmer service, and high-end resort dining often mirrors American expectations — but the hole-in-the-wall place a local recommended probably won't.

Second, "island time" is real. Forty-five-minute waits are routine, and some Barbados restaurants reportedly run two hours or more. Dishes like oxtail soup and jerk chicken take hours to cook properly, and kitchens won't rush them. If you're travelling with kids or need to eat at set times, arrive early and bring patience.

Third, tipping works differently. Many islands add a 10-15% service charge to the bill automatically — Trinidad and Tobago, the Cayman Islands, the Bahamas and St. Lucia among them — so Americans often end up tipping twice. In Puerto Rico and the Dominican Republic, tipping works more like the US, where you add it yourself.

Fourth, dress codes matter more than you'd think. Swimwear and flip-flops are fine on the beach but not at dinner. Upscale spots like Perle at Grand Cayman's ONE|GT explicitly ban beachwear, and even resort buffets can enforce it — one traveller reported being turned away from breakfast in swim trunks. Pack a collared shirt or a decent dress and you're covered almost everywhere.

Finally, don't ask for substitutions. Meats are marinated the day before, stews are cooked in large batches, and a request for "less garlic" simply can't be honoured. Small family-run places may also sell out entirely — a running joke is that the best Caribbean restaurants have nothing left on the menu by the time you arrive. Flag genuine allergies and staff will usually steer you right; swapping a side dish is generally fine too.

The takeaway for holidaymakers: slow down, read the bill before tipping, pack one smart outfit, and treat brusque service as a good sign rather than a grievance. Travellers who adjust quickly tend to eat better — and enjoy the trip a lot more.
