Nightclub
Security in nightclubs is provided by door staff, often called "bouncers". Door staff check the identification of people entering the nightclub, to ensure that people that are too young to drink do not enter the club. Door staff also prevent drunk or aggressive people from entering the nightclub. They also escort people out of the club if they are too drunk, fighting, or taking drugs. Door staff may also call the police if they cannot deal with a situation.
