In Wikipedia, there are valuable information about tipping practice in various countries of different continents (http://en.wikipedia.org/wiki/Tip):
A tip is a payment made to certain service sector workers beyond the advertised price. The amount of a tip is typically computed as a percent of the transaction minus taxes. These payments and their size are a matter of social custom. Tipping varies among cultures and by service industry...
From the information there, you can make interesting PowerPoint Slides that show differences of tipping practices between the Western and Eastern countries.
Figure: Leaving some small change on a restaurant table is a common way of giving a tip to the serving staff.
