In my home town of
Glasgow,
Scotland there's a venue for gigs called The Barrowlands. The toilets there are quite strange.
Basically there is a metal pipe sticking out of the ground, about three quarters the circumference of a normal toilet seat. This is half filled with water. You either stand or squat over it and do what you've got to do. On the wall behind it is a button, which supposedly flushes this mechanism, but I've never encountered one that works.
Also unusual is the distribution of urinal cakes. Rather than in the obvious location of the urinals, they're scattered around the floor, in some of the sinks, on top of the cubicle doors. Presumably they have been liberated from the urinals by people who don't feel sick at contemplating such a task, and artistically rearranged.
