Expecting that parents teach their children that there's a time and place for everything is kid-unfriendly???? Sorry, but I've had my fill of going somewhere for coffee or lunch and dealing with screaming kids running around and their parents not wanting to be "authority figures".
I was very upset one night when we went to dinner with her daughter and the grandchild was acting out. Threats were made about this punishement or that, and ultimately, the mother gave in and the brat had won.
