Last place I played with an enforced dress code was in North Jersey.
Sat. night Jackets for men. No jeans ever.
Now the restaurants are all scrambling for every dollar so anything goes. Like they say "as long as your wearing some green"
The lack of hiring entertainment is part of it.
I also have recently seen some preformers who just look terrible. Even playing an outside venue you can look decent.
You have to train yourself to ignore most of the noise and whatever and do your best job. I'm sure most of the players here run into the same situations and keep going.
