Bad customer service is not an excuse for assault, if she cannot deal with mean people she should not be in a store by herself. Once she threw the money and spat on him she crossed the line of proportionate response for bad service.
Again equal justice for all. Both have done wrong and both should be punished by the law, anyone calling for less is wrong.
That is a proportionate response. And it should have been the one dealt out in the first place.
It can not be proven that she in any way meant to cause him harm. He doesn't even allege that he was struck by the nickles that she allegedly threw. He on the other hand went after her with the intent to humiliate and cause bodily injury. You see the difference?
