Trans individuals don't go in there to hang out. They go in, get in a stall, do their business, and hopefully wash their hands before leaving. They aren't in there to strike up conversations.
Does anyone? Really? I mean, if I'm looking to strike up a conversation, the restroom is probably the last place I'm going to try. No - scratch that. That would imply that if I had already tried everywhere else, that I would
try to strike up a conversation in a restroom. And the answer to that is no.
And even if I strike up conversation with you elsewhere, and it happens to continue in the restroom, we're not going to 'hang out' there. Stall, business, hands, maybe wait for you, leave.
