Male cleaners in female public toilets

these days the sexes are interchangeable

Do you mean the toilets dragonfly? I’ve never walked into a public toilet marked ‘men’. Nor seen it vice versa. I suppose there are gender neutral loos but I only rarely see one and wouldn’t choose to use one.

I couldn't care less if I'm bursting !

No I don't feel uncomfortable at all.

I have to confess I feel a bit uncomfortable sitting in a cubicle with a man washing the floor in the next one. None of them have ever offered to leave, in fact they seem to look on me as the intruder for having dared to want to use the loo whilst they are cleaning! I must live in a different area!

I don't find it a problem. These days the sexes are interchangeable. I wouldn't worry if I had a male nurse in hospital and a cleaner is far less intrusive.

My mum, however, would never go to a toilet abroad that was unisex!

Often as a result of cost cutting.
I don't find it a problem and have found that if they are cleaning when you walk in they either ask if you are happy for them to continue or they walk out and come back after you leave.
