I work at a place with a lot of people from southeast Asia. It is not uncommon to be in a stall and look over to see the feet of someone stepping into the next stall just disappear as they approach the crapper.

I don't mind them standing on the seat to squat, but for the love of humanity, please clean up the fucken mess afterwards!

Also, our toilets flush pretty assertively and often they will splash up dirty water from the toilet bowl onto the seat and floor as the auto-flush unleashes.

The weird one is the guy who uses it as a fucken bidet... like, Bruh. Nasty.
