Pretty much just entitled behavior that they should be able to treat a normal venue like a gay club.
Lots of inappropriate shit in public (lots of attempts at sex that were shut down by staff -- handjobs, attempts at blowing a guy, fingering assholes) and having to police the bathrooms so that there was only one person to a stall. The manager had to post 2 doormen at the bathrooms and to ensure that the (very few) women who were there would be able to go into the women's restroom and use it for its intended purpose and that the men's washroom was also being used for its intended purpose.
I've worked bars and have seen similar shit with hetero folks and when folks are caught (ie, fooling around in a bathroom stall) they're usually embarrassed and not indignant at the notion that maybe they shouldn't be doing this or angry that you're intruding. I've also never seen it so fucking blatant or frequent, even at like college student type places where you would expect people getting sloppy drunk and making poor decisions.
