I don’t know. I really don’t. You do see it more often at Chuck E. Cheese. It could be alcohol, it’s crowded and noisy, especially on weekends, and that can be stressful for parents. From what I hear, children generally enjoy the Chuck E. Cheese experience more than the parents do, so perhaps the parents are on edge already, not being particularly happy that they’re there in the first place, and the stress of the situation just gets to them. It’s certainly very odd, as it’s been going on for years. I’ve even heard that parents have actually beaten up Chuck E. Cheese himself.
