My problem is really not the noise. We only have one table for both teams to share. When the wife and kids show up, the table is full of food, drinks, and toys and other stuff, leaving no room for anything else. And trust me, at least one drink will fall off the table before the night is over.
Now, I do not blame the kids, kids will be kids, but the parents, especially the one bowling, should know better.
My league inserted a rule a few years ago. If they bring their kids and they misbehave, the parent will get one warning, after that, the bowler will not be permitted to finish the night. Fortunetly we never had to enforce the rule.
