How do you figure that not telling the hateful customer to leave is customer service? It isn't. Customer service is supposed to take care of all the customers, not just one. Customer service doesn't exist in most companies anymore. The people that work there couldn't care less whether or not they get your business and that's why they don't care whether or not your happy with the service.
Sure and I'd like to see answers reserved for serious questions instead of dumb ones, but that's not going to happen.
Really though, if I were eating at a restaurant I wouldn't enjoy seeing two adults cussing each other out.
And I wouldn't enjoy a display of brutality and violence anywhere.
If a lawsuit were truly frivolous it wouldn't go to court, let alone need to be reversed, a judge can throw a case out on its merits now. What I would like to see though is a company that would admit its errors and pay up without wiggling out of its responsibility. Even if it costs them.
