“Caveat: It has been noted on the discussion page that this list includes examples of common etiquette, superstitions, linguistic guidelines, preferences in terminology, cultural tendencies, local laws, regional customs and many other occurrences which are not correctly defined as faux pas. Nevertheless, the following list contains useful generalized information about ways that one might breach social expectations in various countries. Note that changing attitudes and multiculturalism within countries means that some entries listed here may apply to the social expectations of only a few individuals. To avoid giving offense, it is best to use a conservative and observant approach in any social situation where one is unfamiliar with cultural expectations.” (Thanks kottke.org!)
