A butler is a person who works in a house serving and is a domestic worker in a large household. In great houses, the household is sometimes divided into departments with the butler in charge of the dining room, wine cellar, and pantry. Some also have charge of the entire parlour floor and housekeepers caring for the entire house and its appearance. A butler is usually male and in charge of male servants while a housekeeper is usually a woman and in charge of female servants. Traditionally, male servants were better paid and of higher status than female servants. The butler, as the senior male servant, has the highest servant status. He can also sometimes function as a chauffeur.

A cup-bearer was historically an officer of high rank in royal courts, whose duty was to pour and serve the drinks at the royal table. On account of the constant fear of plots and intrigues, a person had to be regarded as thoroughly trustworthy to hold the position. He would guard against poison in the king's cup, and was sometimes required to swallow some of the drink before serving it. His confidential relations with the king often gave him a position of great influence. The position of cup-bearer has been greatly valued and given only to a select few throughout history.
