SXSW Bully sucker punch. Justified or cheap?

OK, here's a video when nobody stepped up to help. This vid does not show how it started, the black girl came into the store and butted in line, the guy on the phone was telling his gf about her doing that and she started going off on him for no reason, then as you can see when the pizza manager tried to step in, she spit in his face. Then her drunk boyfriend came in and started punching the guy and would not stop until he was beaten senseless and those penisless wonders in the store just stood there and watched the poor guy get beaten almost to death...and nobody helped.
