This is an AMAZING idea, and something I've made countless passive comments about before. I've had so many meals ruined, at all different points of the day, by crying/screaming children, whose parents seem to have developed a kind of immunity, and manage to ignore them completely. My friend can do this. He had a baby brother, and much like I tune out music at restaurants, he tunes out kids. I can't do it. I really don't want to hear a slippery-slope argument. They do nothing for debates. This isn't a slope issue - it's a solution to a problem with well defined boundaries. You can't simply force customers with disruptive children to leave because then you have issues with securing payment. How do you define disruptive anyway? Having a defined age is a practical means of getting rid of disruptive children. Most parents aren't going to reasonably say "well my kid still cries and screams, but just turned 3... so he should be ok." However, the underlying problem: Parents who take their children to restaurants (or anywhere public) should be respectful of their surroundings. If you're using public transit, or eating out, make sure your kids aren't causing trouble. If you can't control them, the you leave. Your kids are your own responsibility, and just as I leave a place when I feel uncontrollably enraged, you have an obligation to leave when you can't control your children, and they're disturbing others. If everyone did this, there would be no need for these kind of rules. I can't believe someone didn't put in a rule like this earlier.
