Whenever I see a clip like this I wonder what inconsequential bullshit started the brawl. The one in the blue vest is an employee, I assume. There's what looks like a half rung order on the belt, could there have been a minor dispute over an item's pricing? Perhaps the ape in pink picked up an item that was placed on the wrong shelf, and therefore was above the incorrect placard that listed the price for a different item. This has happened to me before, where I ended up purchasing an item that cost more than I thought it would. I grumbled annoyance at my own lack of due diligence. Ot maybe it wasn't such an innocent mistake, maybe the ape had attempted shoplifting by placing an expensive item inside a cheap container, and the cashier discovered it and it escalated from there. Who knows, trying to apply logic to these creatures is an exercise in futility.
