Did the black woman jump the counter too? It looks like she got hit at 0:35. Then you can see the guy whack the male, on the floor behind the counter, a few times when he falls down. It appears the "whacker" then asks the woman if she "wants some too?". Then he proceeds to whack her, again, as well.
That's whats up.
The white woman was screaming like it was going to do something. "Stoppp!!! STOPP IT!!!, NOOOO! NOOOOO NOO NO NOOOOO!!!! STOP!" ("Think of the CHILLDRUNNNN!") lol
The word "no" means jack crap to someone with adrenaline running through them.
