Squat Manners

In many parts of the world the pit toilet is a common experience for bathroom neccesities. Most people in the USA are unfamiliar with these monuments to poo efficiency, so I'll take a moment to explain.  The toilet is basically a hole in the floor, with non-slip foot rests on each side of it.  One backs into the pit toilet, squats, and does what comes naturally.  When done, one either washes the remains down the hole with a bucket of water, or in more progressive places can actually flush the pit toilet with a provided tank of water by pulling a handle.  Where there are only pit toilets, one must develop squat muscles over time in order to effectively use the system.   While visiting a toilet yesterday in Beijing, we found ourselves in such a facility with small half walls dividing the pits.  Without much personal space, I wondered how one would go about doing his poo business without being intrusive or offensive to others engaged in the same activity.  My question was quickly answered, as a guy entered the facility, looked the situation over, and found a spot two down from us instead of using the hole open in between us.  There seems to be, thankfully some limit to expected social interaction and togetherness here.
