The worst is public “traditional” toilets in Japan. A hole in the ground with a T-bar to hold on to when you squat.
Not everyone hits their mark. Unbelievable.
(Although Vietnam may have something similair.)
I have never been anywhere (other than camp) that didn’t have civilized bathroom facilities ... although they were on the edge regarding toilet design in Amsterdam. One would think that an obviously superior design would emerge which everyone would adopt.
Potty talk. Went camping for a few days with several people last week. Took a plastic yard chair and cut out a circle in the seat and glued a toilet seat onto it.
Put up a tarp enclosure and dug a hole.
As good as an outhouse!
Strange, 75% of Japanese have Bidets, in fact the Bidet is a measure of prosperity.
