I personally think that was a very funny and creative solution to the problem, but then again I do have an extremely twisted sense of humour. Nobody really got hurt (except for the guy that got bitten, which I'd argue actually makes him the victim here), but after the initial shock, I'm willing to bet that a) the kid never went around biting anyone again, b) the mother started to do her job a little better and actually gave a shit whather kid was getting up to and c) that shop was just a little safer. None of that would have happened if the guy who got bitten just accepted it and didn't say anything. Personally, if I ever find myself in a similar situation, I will almost certainly be doing the same thing, and I thank you from the bottom of my heart for sharing this brilliant idea with me. Bratty kids and uppity parents who let their bratty kids run wild only to side with them when they do something wrong are among the lowest people in society.
