We’ve all been in public places where kids are running amok, getting underfoot, and being a general nuisance, while their parents are either unaware of what’s going on or unwilling to do anything about it.

Dan McCauley, who owns a bakery/coffee shop on the north side of Chicago, was fed up with those parents and kids, so he put up a sign: “Children of all ages have to behave and use their indoor voices when they come to A Taste of Heaven.”

Amazingly, some parents were upset with him and started a protest and boycott. Yesterday on my show, he explained why he did it, how unaware some of these adults were of their bad parenting skills, and what’s happened to business since.
