Tip a Japanese waiter, and they'll be insulted. Don't tip an American one, and you'll get the same result. 

A gratuity, the amount paid on top of the actual bill, is typically paid directly to restaurant and bar staff, taxi drivers, hotel workers and other service personnel.

Although essentially a voluntary appreciation of the quality of services rendered, tipping has become customary or even expected in some countries. In others, it's positively frowned upon. So where should you pay – and how much? This map should keep you out of trouble.

 

Oh, and remember, in some cases, tipping is illegal: don't ever try to offer a gratuity to government workers – that's bribery! (See #863).

UPDATE - whototip.net is a comprehensive guide to gratuities per country and per sector (restaurants, hotels, tour operators, etc.) It also provides information on whether cash payment is preferred. Thanks, David Weintraub!
