Tipping
From Openwaterpedia
verb - A tip is an amount of money given by a customer to another (typically, a service worker in restaurants, bars, hotels, hair salons, taxis, etc.) as an appreciation for the service they performed, in addition to the basic price of the service.
Tips and their amount are a matter of social custom and etiquette, and the custom varies between countries and between settings. The amount of a tip can be a specific range or a certain percentage of the bill based on the perceived quality of the service given.
