Don’t wear sleeveless tops into churches in Greece. Don’t tip in Japan. Don’t eat with your left hand in the Middle East. Don’t point with your feet in Asia. These are just a few of the local customs it’s important to know before landing in a foreign country. Otherwise you risk sticking out as the ugly American, offending locals, or simply making life harder for yourself than it needs to be. More etiquette tips that your fellow TripAdvisor travelers have shared—on Twitter—1`include:
