Is it fair for restaurants to ban little eaters? In Monronroeville, a local restaurant, McDain’s, recently decided to ban young children. Alice Roseman, its manager, says kids have bad manners and make too much noise. Other people, however, say the rule is hard to accept. Since it has become a hot topic in public, we caught several local people talking about it.

YES

There is no law stopping restaurants from banning young children. Restaurant owners should be allowed to ban them. Kids often run around and cause problems for waiters and other customers.

----Kate Barker

Kids always cause a mess, but the parents refuse to do anything about their kids’ behaviors. Although kids may be at the center of their parents’ universe, they aren’t at the center of everyone else’s.

------Mike Vuick

Adults sometimes want to talk and enjoy their dinner, but they can’t if a child is crying and running all over the place. That’s why sometimes parents don’t like eating at home. They wish they could have a good meal in the restaurants without kids’ noise.

------Dale Levitsky

Banning kids from restaurants is a bad idea. If kids were banned, many restaurants would lose business. Even if restaurants gave customers the chance to buy take-away meals for their kids, many families would probably still not eat there.

--------Nicholas Song

Restaurants owners who ban kids think all children are wild and rude. But that’s not true. Most children’s eating behaviors are good enough. Even though some kids do have bad manners, banning is not a right way to teach them. I think how a society treats its children is important. After all, all kids are people, too.
