I agree with the long red haired comedian woman who said others should be able to say something to parents about a child's behavior. I was so pleased to hear what Dr. Phil said about his son in the restaurant. So many parents have gotten away from just pure politeness of removing children from public when being naughty.  
 
I have 3 children, and I do remove them when they are naughty. Case in point, one time at the airport (international flight) this woman had her son (about 3-4 yrs) in the waiting area & the boy was just obnoxious. He would rumage through other children's bags (honestly!), & when the other child's parent would remove the items from him & take back their own child's luggage this boy would scream nonstop at the top of his lungs!  
 
The mom was sitting next to me& just said calmly, "those are not your things. The man had every right to take them away." The boy kept screaming. The mom actually attempted to make excuses for the child rather than do something about it. I had enough & got up to move to another area, but not without commenting, "you REALLY need the Super Nanny!" The woman was appaulled, but not nearly as much as the rest of us passengers who thought, "Oh no! we have to get on the plane with this kid!"
