And yet as someone who only flies 10-15 times a year and being a terminally online dipshit, I have seen this happen. Not like one of those TikTok videos with fisticuffs, mind you.

I remember as I was annoyed that this whole thing was holding up my flight. Family asked someone to move, they declined, family kept insisting. Boarding line was getting held up due to this. FA arrives, starts imploring the man to move his seat, obviously just trying to get boarding complete so we can all move on with our lives. Eventually the man got up & changed.
