I just couldn’t quite remember. It was a long time ago.
I know the first night we were in a temporary or processing barracks and that one probably had no stalls. But I was in a daze that first night. My first time flying getting there and a very cold bus trip to the base.
^^I remember waiting for the TI to show up at the airport [he was running late] to get us on the bus, and I was still playing a video game. Needless to say–we started off on the wrong foot!
During my father’s WWII service (if I understood correctly), his barracks was the former civilian changing rooms on a beach in California. I never asked where the head was and what it was like 
It may be a problem if children use them and they would be exposed to public viewing.
The pit toilets in some Boy Scout camps (like Philmont) were primitive two-seaters. They were called “pilot and co-pilot”. We kept looking for the mythical “pilot and bombardier” two-seater.
There was a mall in the Champaign-Urbana (Illinois) area that had half-high toilet dividers. The walls were about 40 inches tall, so you could easily converse with your neighbor without seeing their private parts. At least, until they stood up. (To stop drug deals, of course.)
Great Lakes, spring of '82 – ditto, except that when you walked into the head you were looking straight into those doorless stalls.
While it’s been steadily on the decline for the last 50ish years, it’s always seemed like the gym class syllabus had an extra item just for the boys. That they have to all be naked in the same room, at the same time, at least once during each class. Whether it was swimming naked in the 60s or being required to shower, and shower naked, in the 70’s or not having doors on the bathroom stalls [whenever that was, sounds 80s-90s-ish].
“Ah say, you’re built too low, son. The good ones are goin’ over your head.”
LOL! 
Not yet?
MREs have a small wad of toilet paper.
Back in 1989 mrAru and I visited Eugene Oregon via whichever route went through Idaho, and one of the rest areas on that route [and it was a major route was a 2 seater, and if you wanted to wash your hands you had to jump a fence to a cow trough. Looking at a map, Rt 20 I am pretty sure.
No doors? No problem…
Is there a different way? If you sit the other way, where are you supposed to put your comic book and your chocolate milk?
Hey, when life gives you lemons. . .
I was at a drive in movie theater once in Indiana, PA that had an old cast iron bathtub in the men’s room instead of urinals. That was weird.
A dive bar I used to frequent had urinals made from cut open beer kegs. Led to a lot of jokes about ‘recycling’.
Doesn’t your work provide a restroom?
I don’t know if no stall doors is illegal, but it seems illegal if your employer doesn’t provide you restroom facilities.
I was thinking of that scene from No Time For Sergeants.
I lived in a dormitory my first year away at college. Shortly after move-in, we had a floor meeting which covered some new rules. The two showers (per bathroom, two bathrooms per floor) were laid out such that they were adjacent to each other with a wall between but no doors or curtains. A new rule was to only let one bathroom’s shower be used at a time. I’m not sure what had happened the year before to have this put into place.
Another rule, possibly related, explicitly banned masturbating in the showers. The RA said something like “We may never know if it was shampoo or jizz.”
Welcome to dorm life!
