People who live in touristic areas, what are the rudest behaviours you've seen among tourists?

I've lived in a very touristic city for basically my whole life, so I tend to avoid tourists whenever possible.

Stuff that I see frequently that annoys the shit out of me:

• littering
• pictures, videos, tiktoks and similar shit EVERYWHERE
• tourists getting way too drunk and causing trouble in various settings
• driving like morons (please google traffic laws before traveling somewhere)
• large groups walking slowly side by side, blocking entire sidewalks
• complaining about everything, especially stuff caused by tourism, like long lines or long waiting times
• acting entitled towards people trying to do their jobs
