(A mother and her young son come up to me, each with their own items to buy. I finish ringing up the mother and start with the little boy.)

Mother: *to son* “Isn’t it nice to buy your toys with your own money?”

Son: “Yeah.”

(The son begins to reach over the conveyor belt for some candy.)

Mother: “Oh, you don’t need that. Put it back.”

Me: *to the boy* “Your total is $6.66.”

Mother: “Oh, no, no, no! Buy that candy!”
