I remember being in Japan and finding the toilets at this new university building very strange. The high-tech seat had a control panel next to the throne with about 20 buttons, all with Japanese characters, so I had no idea what they would do. Rather ominously, one looked like a red emergency stop!
But in-spite of this fancy stuff, they seemed to have omitted any hand drying facilities. I saw someone had left a few paper towels, and I thought maybe it is work in progress, so next time I tried a toilet on the floor above where I was working. Exactly the same!
Edited to add: I decided not to experiment with my own bottom, and unfortunately there were no volunteers to find out what all those buttons did.
