Recently, whilst camping in Arches national park in Utah this odd eccentricity of american cubicles was brought home to me by a deeply unsettling experience.
I wake in the middle of the night to the unpleasant realisation I have to shit. Out of my sleeping bag I struggle and into my cold weather gear (there's a 4 inches of snow on the ground and air temperature is hovering around -8) and stumble bleary eyed to the nearest toilet block by the light of my head lamp. On the way, I notice a family has arrived really late to the site and is setting up their tents and don't seem to happy about the cold. I enter the toilet block and settle into a cubicle to take care of business and due to the lateness of the hour my head drops to my folded arms across my knees. A couple of seconds later I look up and the light from my head lamp reflects off a single black eye staring in at me from a snow white face at waist height (if I was stood up) through the gap in the cubicle. I yip like a startled 10 year old girl (but ironically maintain sphincter control) and the eye and eye owning face shuffle away into the darker recesses of the block (which is unlit at night as the lights are solar powered). Close to hyperventilating I finish up and slip uneasily out of the cubicle cursing my love of Japanese horror films. I discover two children in the block. Both have large suitcases with them. One case is open and it's child guardian is wriggling into the packed clothes within like a grub into dead flesh. The other child stands silently staring (sleeplily or malavolently i couldn't tell) at the first. The next morning I decided they were the kids of the late arriving family who were seeking shelter from the cold and snow whilst their folks setup camp and not a pair of diseased twilight zone inhabitng, suitcase dwelling demons as had crossed my mind as I fled from the toilet block through the snow the night before.
USA toilet fear!
