Etiquette 101: Tipping Guide

Whom to tip, how much to give, and how to give it—in more than 35 countries around the world.
So you just had a five-star meal in Qatar. Or went scuba diving in beautiful Bohol in the Philippines. Well, lucky you! But how do you express your appreciation for the service you received? Are you in a country where tipping is customary and required? Appreciated but not expected? Or virtually unheard-of? The truth is, tipping rules vary by country, by region, and by scenario. A modest rounding up of the check may be fine in some places and insufficient in others. A few small bills left on a night table might be gladly picked up by housecleaning staff in one hotel and scrupulously shunned elsewhere. Such uncertainties can throw an uneasy shadow over even the most exhilarating jaunt in a new land. That's why we've spelled out guidelines for the most common tipping situations in more than 25 countries, from Switzerland to Syria to Singapore.
