Then he should have explained himself to the first guy who challenged him. Instead, it looks like he verbally escalated the situation.
You don't have any idea what the guy did or said since the video started after the confrontation was in progress...
The fact is; he was clearly trying to avoid conflict while being adamant about getting to the counter in spite of getting beat up in the process...For whatever reason he had to risk bodily harm, I can't believe it was just to be first in line...
