Well, like some others said a peep show is not a park where friends can hang around
The guys you saw watching free porn at the entrance are mostly male prostitutes. The manager has probably his cut whenever they meet some client. I went to these places some years ago, before porn became available in the comfort of our homes. It felt so weird to pass by these guys. I still remember when Oliver K. wrote that "they look at you as if you were a big steak"
On the other hand, I can testify that the guys who work at these peep shows are very rude. I know what ethnic background the starter of this thread is referring too and I don't think it is a crime to point to some unacceptable attitude to criticize the attitude of
some people belonging to a given group. Only generalizations could be flagged as racism.
