Teenagers shouldn’t waste space at the airport bar!

About a decade ago (I was 30), I was on a work trip. Decided to work on a presentation and grab a beer and a burger at the bar at a restaurant in the airport during a long layover. Boomer with his co-worker (both wearing suits) complain that there’s only one seat left, which happened to be next to me. The younger guy said he didn’t mind standing, while the older guy complained that teenagers shouldn’t be doing homework and taking up space at the bar. I looked at the bartender, who knew how old I was, and he said to the guy „the dude is 30. He’s older than your friend right there.“ Young guy just said „lucky you!“ while the older guy rolled his eyes and turned away from me. Now in my 40s, I’ve grown a beard and have a couple of greys poking through but I still look younger than I am.
