When I was a small tot I threw a tantrum in a grocery store because I did not get something I really wanted. I only did it once. Getting my behind beaten RIGHT IN THE MIDDLE OF THE STORE IN FRONT OF EVERYBODY by my mother broke me of the habit real quick. Those were the good old days folks, and now they are gone forever.
My Pastor tells a story of a trip to the grocery store. He told his kids they were going for three items and nothing else would be bought. Sure enough, one of his daughters started throwing a fit over a candy bar. He raised his voice and said, "Excuse me, everyone? My daughter wants to throw a temper tantrum, and she'd like to have everyone's attention." All eyes went to her...and she melted into the background.
