1) Do you have separate gents/ladies toilets in your house?
No. But then how many if your husbands/brothers/life partners/fathers would barge into the room while you were in the toilet.
2) In pubs, clubs, at concerts or anywhere it is really busy you will see women using men's toilets to avoid the queues
Women shouldn't be in the men's either.
3) An office where I once worked had 16 staff split equally M/F and two separate single toilet cubicles. Staff voted unanimously for the toilets to be unisex, and never regretted it
So you we're actually asked then. and everyone who joined the staff after would know they were unisex and expect
It.
4) Trains and planes have unisex toilets
Yes but it's one loo behind a door. No one's in their with you.
5) A disabled toilet is NOT for the exclusive use of disabled people - the regulations make this quite clear - it just means it is equipped for them to use it. Think of small establishments where the only toilet is disabled accessible, and again, the toilets on trains
Again if it's just the one universal toilet then it's for everyone
If there are men's female and disabled you use the right one. And you certainly don't use the disabled toilets when out of 2 other rooms with multiple toilets in are provided. Leave that one toilet for someome who actually needs it.
