This didn't directly affect me as I have use disabled toilets, but I was out earlier and there was one male, one female, and one disabled toilet. There were 3 men and 1 woman waiting. One of the men was about to go into the disabled toilet when he saw me. I have no choice but to use disabled (wheelchair user). The female toilet became vacant and the man walked towards the door. The woman waiting was quite young and looked surprised but didn't say anything. I'm far from young and used to speaking up for myself, so I pointed out that it was a toilet for females and unless I was mistaken he wasn't female. He said no but I'm desperate and went in anyway.
So not only do women have to put up with men pretending to be women, we now have a man who decided he was going to use the women's toilet anyway!
