I read all the time about how people staying at Pop and the Values can hear showers running and toilets flushing in the night. I'm a heavy sleeper, so these things don't really bother me... but, it makes me wonder about a foreign custom that I recently experienced. When we were visiting my sister and her DH at their apartment in Switzerland, we were told that we couldn't flush the toilet after 10 PM. That country (and maybe others) has several of these "rules" that people follow as common courtesies to their neighbors.
My question is... I wonder why this custom didn't make its way to the US? Is it because people find it gross or what? It would certainly resolve the complaints people have at hotels.

, but when I'm on vacation I want to be able to flush my toilet! And I've never been at a hotel in Europe with this rule!

We do it not to disturb others but it is not a rule in our Country
after 10 p.m.
