I saw a video in which some characters of the Fallout tv show open a fridge and find an alien and just toss it out because they want the working fridge. I’ve never understood (or really bothered with) why Fallout had the nuclear “event” which triggered the use of the shelters. Was it an alien invasion?
You’re right, that would be really stupid, just like Americans fighting over guns in a zombie apocalypse (ammo and medicine are the real limited supplies, especially if you suck at fighting zombies), or killing off a couple percent of your population because wearing masks is uncomfortable. So it seems very plausible.
