In defence of doorman in general, the only two that I have known at all well are not unpleasant or unsafe characters as far as I can tell.

One is a bit self-righteous and not as bright as he thinks he is - went to a special school - was involved in minor theft when much younger but is essentially OK. Working as a hire-car & coach driver anyway, these days. And a good raconteur.

The other was a very conscientious storeman who, annoyingly, left to enter an uncle's fish-and-chip business. This hadn't worked out, so I later saw him in passing on the door of a local pub - his normal stolid self.

Didn't know CAMRA didn't list pubs with doormen - thank you Jack - but this follows my own judgement in choosing pubs.
