About 45 years ago, when I was flying all over the world in C-130s, I actually went to a Bumfuck Africa type place. It was a real **** hole. In that part of the world, a bathroom was a 3 x 3 tile square that slanted down to the center where there was a round hole. You squatted over it and took a dump or whatever. Then you used the hose to rinse everything down into the hole. If you had to spend the night, you relied on either a US consulate, if there was one, or the US Air Force paid transportation representative to tell you where it was safe to eat and sleep. Not a very nice place.
