Bouncers

Hey guys,
Sorry I haven't posted yet!
I'm really into the idea of discussing bouncers and how they affect a night out. I, too, have had experience with being turned away because of the way I was dressed (mainly to do with the fact I was wearing trainers). I also had a friend who was turned away from a club for wearing shorts in the summer but I think it was more to do with the fact that he looked like he could cause trouble. This club was a student club so they had no dress code and this seemed quite ridiculous as it's a sort of "anything goes" kind of place.
To research further, perhaps those of us who work in bars/clubs could ask the bouncers we work with what they look for when turning people away/kicking people out? We could try and determine what prejudices, if any, they hold and how they affect their decisions.
Sorry again,
