Sorry but if I worked in that store I wouldn't break up shit if you get injured breaking up a fight and you are a cashier or a stock clerk and are not security you will be denied workmans compensation because breaking up a fight is not on your job description. Call the cops and let them hoes fight until they kill eachother or get tired of fighting. Then also if you touch one of those nasty bitches in the wrong place while trying to break them up they may try to have you arrested for sexual assault...it literally had happened to a man.
