Anyway, it's never a hassle. Men are just bemused when a woman is forced to go in there and nobody really cares.
Consequently, I've accidentally walked into a women's room a couple of times. It's not like in the movies where a bunch of women in frilly underwear clutch themselves and scream. They just give me that slightly bemused look and I just get out of there as fast as I can.
The why is simple.
1. Restrooms typically have the same size footprint, but you can place 3-4 urinals in the space used by 2 stalls. So for the same size room, you get more capacity.
2. Urinals: just unzip and go. Easy for the guys. Sit-down toilets, clothing has to be arranged to go, and re-arranged when you’re finished. Which adds time to each “transaction”
And since most of the traffic is to dump fluids. . . .a men’s room is a generally a lot quicker to get through. . .
