Erm, how exactly do you think we’re going to educate people on the “normal” way of using a toilet, if it’s not educational signs above toilets? Do you imagine some kind of toilet license? Where people have to take toilet train and demonstrate their competence in front of an examiner? Or perhaps at every border, non-citizens are given mandatory toilet training. Or perhaps you’re gonna follow everyone into to the toilet and tell them how to use it correctly. Your issue is with people not learning your native culture, but your evidence for people not learning is educational material that teaches people your culture. So it does rather seem your problem is that your specific culture isn’t the world wide norm.
