Yeah here in the good ol (hahahaha) USA most establishments have a separate “restroom” for men and women which consist of a row of sinks for washing up and a number of stalls for toilets (and urinals in men’s rooms of course).
Sometimes the urinals are just in a row on the wall with no dividers between. But there’s usually one or two disabled stalls as well, although they’re not locked in any way.
If I’m not paid for ALL the time I am required to be on-site and available to my employer (including for security purposes), I’m finding another job asap. Don’t give your time away without being compensated for it.
