whether there were women in there who would have indicated which cubicle he'd gone into, or whether the place was empty and there was only one closed door, so the bouncer wanted to check he hadn't pushed a woman in there and had a hand over her mouth.
...
I suspect here 'knocked on the door & said "oi oi are you all right in there? Can you come out please, we've had a complaint"' is identifying as cubicle peering.
Well, actually, I suspect this entire incident is Identifying As A Thing That Happened, but whatever.
This! The people on this thread who are suddenly more concerned about a dishonest man's account of what a bouncer did or didn't do than the fact the dishonest man was in the women's toilets are kidding themselves if they think the bouncer is the bigger problem.
You're a bouncer. Women have complained about a man in the women's toilets. (Is he in drag or just dressed as a man?) You go in. You call out. Any answer? Have you been ignored? Have you dealt with assaults and overdoses in toilet cubicles in the past?
What do you do? Just stand and wait? For how long? Have you asked women to leave the toilet? Is there another toilet for them to use? How long are you going to wait to see if the person ignoring you is dead or has someone else in there?
Interested to hear what some people's preferred rules of engagement are in this situation.
