Waiter

A waiter is a man (female waitress or the gender-neutral "server") who "waits" on tables, often at a restaurant.

Waiters' and waitresses' duties include preparing tables for a meal, taking customers' orders and serving drinks and food in a restaurant. Depending on the type of restaurant, this may involve other uncommon duties, such as a Western-themed restaurant may require waiters and waitresses to line dance.

Certain fantasy books (notably including '\'The Hitchhiker's Guide to the Galaxy'' series by Douglas Adams) refer to an alternate math invented and used by waiters. This is an extension of traditional mathematics which takes into account not only the mere numbers involved in a calculation but also the context of the situation where the calculation takes place. It is a wholistic approach to mathematics and much more complex than normal mathematics, which results in it not being reproducible and financially beneficial to the waiter.
