Midwatch Discussion -- Worst Toilets

Remember the discussions you'd have on the midwatch in Control or Maneuvering? The ones where you always knew deep down that you really should be going over the stuff in the Night Orders you were supposed to be discussing, but instead got into a 3 hour conversation about something like "things on a submarine named after animals" ("White Rat", "Bear Trap", etc.)? The incomparable ninme posted about Asian toilets a few days ago, and that got me thinking it would be a good topic for conversation...

The first time I ever saw a "squat toilet" was in a bar in Korea. Luckily, I only had to stand while using it; I never did actually use it for #2. I still have no idea about what the unwritten code is for their use (there were three holes in the floor of the bar's bathroom) -- do you just drop you pants around your ankles and squat in the middle of the room?

So the topic of discussion is: what's the worst / most interesting bathroom you've run across in liberty ports around the world?
