How do you deal with parents who won't disicipline their children?

I don't see that very often, but I guess I usually ignore it...

There should be a well-placed sign, maybe on the front door, which states something like, "Parents of young children must have control over them at all times while in our store," or "Parents of young children will be held fully responsible for any damage or injuries." In that way, you would have every right to inform the parent that they must discipline the child or leave the store. It would also give you the right to stop the child from potentially dangerous activities until the parent can be located, or she/he comes up to you looking like they are about to bite your head off. I realize this is not good public relations, but it beats the alternative of a child getting hurt or merchandise being destroyed. At least, that's my opinion.

I don't wonder why these kids are undisciplined. Even their parents are misbehaving. Well, anyway if the kidswill hit and break anything in the store or bring any merchandise into spoil due to their misbehavior, the irresponsible parent anyway should pay is it not??? Well as for me, when I come across kids like that... I always give them my sharp- tiger look and let them show my disgusto. If I am the staff of the store like you are, I believe I have the right and the responsibility to stop them to protect the store. No need to quarell with the parents just tell them politely that the store has policies to follow. Thanks1
