What’s one thing that makes you instantly think, ‘That person is definitely not from around here’?

I grew up in a town that used to be somewhat famous or at least well known for the amount of pubs it had per square mile. I was born after a lot of the pubs disappeared. We grew up using pubs, including ones that no longer existed as landmarks so to speak. It's right next to <insert pub name>. The pub got knocked down 20 years before I was born and there is nothing there that even shows a pub once stood there. But that's simply how our parents gave and received directions. I don't live in the town I grew up in anymore, but I'll sometimes get jobs that take me there and I over hear conversations of people a lot younger than me still using these non existent pubs as landmarks. So yeah, if I hear people from my old town, especially my age and older, not know where this non-existent pub is, it's usually a give away that they're not from round here.
