I'm gonna say it's policy that most establishments of that sort don't interfere and call the cops instead. Its a liability against the company. If they injure someone during the scuffle, the company can get sued. If you look at a similar vid, the manager got jumped when she tried to break up a fight and make everyone leave. You cant knock anyone for not stopping a fight and its not about courage. People carry blades and guns, MALE AND FEMALE, and if anything, the vid helped show how violent and ruthless some people can be. Best thing for the average person to do is call the police. Someone just happened to be recording and whether its for the wrong or right reason, it only helped her case. Thats just IMO. I'm not speaking for me personally, but i know most people arent capable of stepping into that situation and having it end peacefully.
