Growing up in West Virginia, I was in a moderately sized city (40k people) but when traveling to smaller high schools for football games, you'd often find a shared latrine as the bathroom, and everyone who needed to pee would just crowd around a long sink thing and just let 'er rip. No idea what it was like in the ladies'

Open troughs are fine, toilets facing each other with no partitions is a bit far. I grew up rural but not that rural.
