@one I've encountered a dude like that on a long train ride. Mid 40s, watching a movie on high volume in a full train. The ticket inspector told the guy to keep it down. He replied "I dont have headphones. What am I suppose to do?!"

Headshaking ensued and people gave him the look. 15 minutes later he realized finally he's being a dick. I never shared this story. Thanks for the opportunity.
