So many people are saying this yet not understanding that paying for something and using it does NOT make you immune from being called an asshole and facing criticism.
That's alight. Better to use words, than actions and punch shit.
If I'm inconveniencing someone, and don't know it... I expect someone to let me know, and if I can adjust things I do. There's a way to do that.
Similar situation - on a plane, I don't pretty much ever recline... in full upright position, and the guy behind me is punching the back seat like nuts- every 3 or 4 secs. I let it go for a few min because I was hoping it would die down. It didn't, so I turned around and said "Hey man, when you hit the screen, I'm feeling that... is the screen broken?" I thought maybe the channels or the volume button were f'd up. And he laughed and apologized because he was playing Tic-Tac-Toe on the screen and he was getting into it. He said "oh, I'm sorry. I'll do it differently..." and he did and it all worked out.
There are ways to talk to people.
