Yes they are. They're usually deadbeats who feel this little power they're given makes them rulers of the freeworld....when in actuality they're just fat middle aged blokes who can't get laid.
I remember giving my US id to a bouncer in England after saying "Hi, how you doing?" he looked at it for about a solid minute and then said sorry you can't come in. I told him he was a fat tw@t and walked off laughing.
