I wonder if the OP has used toilets in China (outside of nicer hotels and such).
The problem there is not so much the fact that they are often holes that you squat over (which I have seen in Switzerland and Italy as well), but that "flushing" is often just a small ineffective trickle of water that makes you wonder why they even bothered to have a water supply to the toilet. The sights and smells can be rather crappy.
