I used Primark changing rooms for first time about a month ago, didn't even notice they were mixed. Can't see the problem myself. There was a very helpful member of staff available the whole time I was there. Lots of people around, what was likely to happen?????
As for toilets. I was in Hyde Park following weekend, desperately needed a wee, found a toilet (ladies only) stood in a queue for over 30 minutes getting more desperate as I watched the men walking in and out of the gents (no queue) and wondered if the security guys would allow me to use the gents in these days of equality
🤣🤣🤣🤣
