I've been to ~15 countries in Europe, a couple in Asia and the USA. The latter was the only place I've witnessed it. That's not to say it's the only place it happens, but it certainly seems anecdotally to be a rarity. Maybe instead of a snide reply to your parent comment you could've given an example of another country than the US to have this issue caused by regionalised sales tax differences?
