A bouncer is a term for a person who deals with disorderly people in a bar or pub.
It has been thought that the word, bouncer, originated from when the said disorderly person would be thrown out and bounce as he hit the ground. Another speculation is that the term originated from the person that stood guard on the bar door bouncing a coin someone gave him to enter the bar on some wood to test whether it was real or counterfeit.
Bouncers are only meant to restrain an individual, but they often are more violent.
A doorman is the bouncer who works the main entrance to an establishment. This is a better paid and more prestigious position, especially since it is common to get gifts from those who want in.
Increasingly bouncers must be certified with training in crowd control and first aid.
