Toilets in America are a world apart from what I am accustomed to in the UK.
The principle difference is the minimal use of walling material to enclose the particular hole in the ground. There's normally a good 12-18 inch gap at the bottom, and, for a man of my height, it's very easy to see over the top if I'm standing even vaguely straight.
There is also quite often a reasonable gap between the door and its frame, and a very flimsy lock to keep intruders from your privacy.
I've heard of a number of inventive solutions to the problem, leading from jamming toilet paper in the crack by the door, to walking into the trap with a pronounced stoop to protect your identity.
It all seems a little "public" for my liking. Bring back the hermetically sealed rooms of my youth.
