Completely agree. This is of course a different type of business, with a lot of risk of personal violation, which is why it is understandable that girls have blanket bans on some people...but I don't know, it does feel discriminatory at times, especially after chatting and booking, and then finding out that they won't see a man, for his ethnicity, or race.
But yea, I'd rather go to someone, who is welcoming.
