NC for this because I know it's a controversial topic and I'm not sure how to feel now it's actually happened.
I went to the gym today and there was a man in the female changing area.
He was wearing a swimming costume designed for women, however, was very obviously male.
I had a look online and there have been a few reports of this happening in this particular gym. There are some tweets which haven't been responded to ranging from last year to last month.
Obviously, I didn't confront him and when I left there were no staff members at reception, however, I am not sure whether to say something next time.
Aibu to say something?
