One of the main arguments though I thought for having separate areas was to create safe areas though. Against things like sexual assault and invasion of privacy that would otherwise be encouraged if both sexes mingled. I mean they could create individualized rooms in a hallway, sure, but then we'd have to have a sink in each one, a blow dryer, a changing station for babies, etc... so costly.

The other thing too, if we're in a store, it encourages shrink to have a bathroom where one person can simply go in and can't be checked on by staff. They could be taking product in there for example and removing it from cases, etc... that's why in large shops we don't tend to see a unisex bathroom and if there is it often controlled with a key. (but in a doctor's office or other small offices they would have unisex or employee unisex bathrooms)
