I think no-kids zones are not justified.

It gives us the thought that all kids are immature and rough. It can make the children feel uncomfortable if their parents could go in but if they can't. The parents would feel the same way because they can't do something as a family so they would feel sorry for their kids. And if no kids zone restaurants increase, the prejudice of children being noisy and immature will grow. If they are noisy, they could just tell his or her parents that he or she is too noisy. That way, the kid can learn something and everyone would be happy.

Think you have a gentle and nice kid who is really hungry. So you went to a restaurant but they say you can come in but the kid can't. You would feel furious! Because of the prejudice, your kid can't go in there. Even though he or she is very hungry.

So I think no kids zone isn't justified. It makes people think that kids are all noisy. Instead of not letting the kid in, let's just tell to the kid or his or her parents. That way, we can make our society without prejudice, and no one would feel left alone.
