Public houses may be owned and operated in different ways. Breweries may own a number of pubs themselves. Pubs may be run as franchises by large catering companies. However they are owned, a pub will be managed by a "landlord" or "landlady". Employees do different jobs to provide good service. Bartenders (also called "barmen" or "barmaids") serve drinks at the bar. In most pubs, the customer orders the drinks at the bar and waits for them to be prepared, then carries the drinks back to the tables or area of seating. In some types of pubs may sit at the bar or remain standing with their drinks. Some pubs hire servers, called waiters or waitresses, to bring drinks to people who are sitting at tables or in chairs. Some pubs also hire people to take away empty bottles and glasses, though commonly the bartenders will do this as well.
