Slow

Too many folk think that doorstaff are thick.
Some may not be too sharp but most are. This extends to remembering a face one night to the next. We see a lot of folks every night but the ones who cause bother, or the ones we think might in future, usually get logged in our sober bored minds, however tiny.

We're not likely to wander round the corner to listen to some drunken muppet 'apologise'. We'll keep where the lights and cameras cover. We don't like being out-numbered, out-gunned or out manoeuvered and we're normally bright enough not to let it happen.

If someone comes up with something new and interesting and it trips us up we'll find out about it sooner or later. Then everyone we work with and know from working with will find out fairly soon. Then the trick stops working and normally only shows it's face when doorstaff change and someone'll try it on thinking we don't pass on this kind of information between ourselves.

We're not infallible, we're not geniuses but we're not too dim to make our job safer and easier for ourselves. Obviously, if you don't like a fellow doorman, you can let them fall into something obvious just for shits and giggles but it's best if they or the punter don't end up with blue light taxis of either sort.
