Most children know they can get away with just about anything in public. The situation can only be dealt with in private. Depending on the child's age and severity of the fit, that can range between a good talking to, a skipped treat or a trip to the men's or ladies' room. For really bad fits or kids old enough to know better, a good pinch works wonders. Pinching can take place in public and gets rid of the notion that you are helpless.
