My sister just got to South Korea (Army) and emailed everyone to let them know she got there ok and such.
She of course felt the need to tell me about the bathrooms in the airport in Seoul. There was one thing in the stall that perplexed her---the etiquette bell. What is an etiquette bell you may ask? Well from what she could surmise, it's a bell you can ring if you pass gas or make any loud bodily noise, but are embarassed for other people to hear.
I really hope she took a picture as that made me laugh. So now I'm desperate to go to South Korea and see this for myself.
Any other "different" things you've seen in international toilets/bathrooms?
