Lets say you're working your job, and a customer comes in, that customer is belligerent, rude and offensive, swearing up a storm of expletive's. What do you do in this case? I think I'd try to ask that person to leave, and if they don't, the police might get called. I try to calm the situation down as best I can, but sometimes you can only ask for help to remedy the situation. What do you do?
