I (24 F) was grocery shopping yesterday night, as I finished up grabbing some last items I made my way to the check out line, the store was fairly packed and I rushed to find a register where the line wasn’t too long, I get in line and wait my turn, as I start to unload my items on the belt a lady About the same age as me walks up to me with a small basket of items and politely asks if she can cut in front of me since she had less items than I did, For some reason this bothered me and I flat out said no as I was also in a rush but now I’m starting to think that maybe I am the asshole in this situation?

EDIT: I would also like to add the lady seemed fairly upset that I declined her request which further makes me feel like the asshole
