I've heard of people online having negative travelling experiences in some European countries with people being cold, rude, distant, or even aggressive. I have never been to Europe before, but I've got the assumption that Europeans are generally very etiquette-driven, and value efficiency with getting through the day without getting involved in someone else's business (especially if said person doesn't speak the language). I'm also wondering if these travelers are often extroverted and are just not used to the more (generally) introverted societies that a lot of European countries appear to have. I kinda feel like the differing etiquette is misinterpreted as rudeness.
