There was only one time I had someone cut me and it was in a supermarket line and it's because he didn't realize the line went back into an isle and when he realized it he was like "oh shit" and went to the back.

But up till that point I just sort of, raised one eyebrow but didn't care cause he had like 2 items and so did I. In fact the line was like me and 3 other dudes with a couple items.

Otherwise I'd have been like "bro wtf" and seen where it went from there.

But also I'm the guy that goes to Aldi and if I have a cart load of shit and someone walk up behind me with like, a couple of items in their hands, I'll just let them go in front of me.
