Interesting language tidbit related to the warm/boiled water custom: a common term for drinking water in Taiwan is 開水 (kaishui3), which literally means "boiled water". The first few times people asked me if I wanted "kaishui" I got confused because I thought they were asking if I wanted boiling water... but cold, ice-cube filled drinking water is also called kaishui to indicate that it has been boiled and so is for drinking. I think those kinds of cultural-linguistic ties are cool in language.. I would love a book that gives you a linguistic tour of the world using words that reflect certain local customs.
