I've told this before but worth repeating:
I was once at the theatre with DD and DH, predominantly female audience. Huge queue for the ladies so I sent DH into the gents to see if it was empty and had cubicles (performance due to start v soon). It was and there were so me and DD nipped in, and I realised there was another woman and child in the other cubicle.
When we came out there was quite a queue of women and children inside the gents' for these two cubicles. There was also an elderly chap at the urinals. And it was clear from his body language that he was absolutely frozen. He must have come in for a piss and all these women came in after he'd started and now he didn't know what to do.
Now, that was a benign situation caused, of course, by the fact that venues never provide enough women's loos.But I reckon in all this talk about unisex loos and what have you that no-one cares about our senior citizens of either sex.
