Ramblings on being a parent Part 3

The main issue I see and have seen through 20 years of retail experience, is that parents don't pay enough careful attention to their children. Parents of children with behavior problems AKA Brats seem to pay more attention to things, how the child is dressed, what the child wants to buy, and less to the important things in life, like is the children running like a maniac through a dangerous area. Parents like those seem to think that the store staff are baby sitters, there for their own convenience.
All of life should be a learning experience. The children should be kept nearby and allowed to ask questions of the sales staff to help learn, not allowed to run lose and break things or body parts.
I can't think that this behavior only happens at stores, I have to believe that behavior like this happens at restaurants. Except the running would be on furniture and through the restaurant, where people seem to think running is both okay and safe, a place it is definitely neither.
