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...
Of course, we don't know what might have been said to him prior to the incident going physical. What he might have said or done prior to the video might have seriously contributed to the toxic situation.

I guess you could see it that way but I saw his interaction with the guy escalating rather than defusing the situation.
To really understand what happened, we'd probably have to be there. From my experience with similar situations in the past. although there might be a primary instigator, there is usually blame on both sides.
