I don't have a problem with unisex bathrooms. I have a problem with everyone in a restaurant going into one bathroom. Even if they are unisex we still need 2.
Or just make 1 large bathroom? Most bathrooms are right next to each other with 1 wall between them, knock the wall down you still have the same space but with 1 or 2 extra cubicles.
Erm no it wouldn't, if anything it makes things harder because there would be more people than normal with the inclusion of another gender in the area.
Instead of having 2 rooms with say 5 people in each, you soon find yourself in 1 room with 10 people, which is more likely to get caught and getting your ass kicked??
