I see your point AOII Alum, but at the same point I work at Pottery Barn Kids. We have toys and things, but they are displays and not to be played with. It's supposed to look like a child's bedroom in the store, not actually be one. If it's a rainy day then parents bring their kids in the store to play. These kids don't just play nicely either, we had these big jumping balls that were blown up as a display and I come back to the area where they are and there are two kids beating the ISHT out of each other with them. In that case the mom had gone to the next store and told them to play in ours!
That isn't a rare instance either. Stuff like that happens all the time. Kids end up breaking our displays and we have to keep putting out more. Our store doesn't have a "you break it you buy it" policy and half the time we are so swamped at the registers that we can't tell who it is that broke whatever it is. I'm not saying that kids shouldn't come in the store, but the parents should teach the children not to play with things in a manner as that they get broken. The parents should have control to some extent so that the kids aren't throwing things or breaking things.
