You try standing out in the cold every night while drunk ********s try to pick fights with you, are rude to you, swear at you, spit at all, act like they are above you and that you are a nobody who only exists to be a bouncer. I think it is easy when you have a think about what it is like in their shoes to see why so many of them act like they do, because they have to presume the worse of everyone, that everyone will be that person trying to get in to sell drugs, or that they might be too drunk and need to go home, or that they will be the shithead who throws a punch at them for no reason.
