Okay so this is pretty mundane compared to some things I've seen on here, but here goes:

I like to get my hair cut at a barber shop in town that has gotten super popular and is ALWAYS busy. It has a sort of punk/rockabilly theme and atmosphere to it that I really enjoy. Their haircuts are also great and relatively quick.

The one problem is the insane wait times because they're walk-in only. Whenever I've gone, besides my last three visits, I've had to wait for about 40min to even get into a chair. Not wanting to give up a barber that I really like, I resolved that I would just show up immediately when they opened. The past two times I've gone this has worked perfectly. This time around, it seemed that I might not be guaranteed a chair right upon arriving. I got there like five minutes before open and there were at least four other parked cars with dudes just waiting and watching the door for when they flipped the "Closed" sign to "Open." I see a guy get out of his car and begin waiting by the door, so I immediately get out and do the same. They open the doors and the guy ahead of me is hanging up his coat and I see that my favorite barber is working today, so I bolt for her chair while the other guy is still hanging up his coat. I don't think much of it, because there's still another chair open for him, and the two of us--the first two in line--will get to have our hair cut first.

But then I sit down and get situated and from my mirror I can see that guy that had been ahead of me sitting in the waiting area, looking PISSED. Someone else must have done exactly what I did and bolted past him and secured a chair while he hung up his coat. So I have to wonder, AITA for zooming to my barber's chair and not waiting for him to get situated, possibly giving someone else the idea to do the same thing?
