This whole floor (hosting six companies I think?) in a prominent office tower has one shared male restroom. Two booths. One is usable for me, the other one the scary thing. Most people, locals included, fight for the single seat..
Once you get a stomach bug and you should have gone to the bathroom a minute ago you'll figure it out :) . Hint: It's like the old days, like we've been doing it for millennia, if not millions of years. https://www.google.com/search?q=how+to+use+squat+toilet
This is a thing for westerners; the squat position (with feet flat on the floor) is really hard to do for a lot of them, iirc mostly having to do with ankle flexibility (for me personally anyway). In countries with squat toilets the people are a lot more used to the position / motion. I guess most people could get by with doing a toe squat, but that's harder to keep balance.
Not sure how I feel about sharing this here but yeah, this should answer some of those questions.
