Considering there's nothing illegal about blokes screwing blokes, I can't see why he shouldn't have tried a surreptitious pick-up in a bar, and gone on to a hotel.

Toilets are built for more urgent physical needs. I would feel severely pissed-off if I had the runs and the stall wasn't available because some blokes were using it for getting better acquainted.

There's a time and a place for everything.
