I work with someone who falls foul of this. Our employer bans guns on site, so he parks on the street instead of the office car park, to allow him to keep a gun in his car. Perhaps Seattle is more dangerous than I realize, but I’d hazard a guess that the likelihood of his car getting broken into is higher than that of him needing to shoot someone.
Until I started blocking everything they shared on social media, I saw a lot of complaining from Texan former coworkers about those signs telling people to keep their guns out of businesses - mostly refusing to shop at places that won’t let them carry.
I guess they’re still good going to the pub though, as far as I remember guns were never allowed in places that served alcohol. Not been to Texas in a few years though, so maybe that’s changed.
