If you're eating with others and intend to split the check, it's best to let the wait person know immediately upon sitting down, so that they can prepare for it in advance. Waiting until the last minute will only annoy them and slow down your checkout.

Tipping your server in a restaurant should always be a matter of personal choice, but it's a good idea to tip a good waiter or waitress; they don't get paid much. The standard tip varies from 10-20%, but 15% seems to be the most common accepted rate.

Some restaurants in America, and many restaurants in other countries, often include a 15% tip directly on the check. Keep an eye out for this practice, so that you won't accidentally double-tip. While the wait-staff won't mind, your pocketbook probably will.
