Story of Maine diner owner who yelled at a noisy 21 month old child with the parents present received international attention. Some support the diner owner, some consider her an absolute boor. Tuesday I was at a store when a mother smacked her crying child on the backside near the exit. She turned and stared at shoppers/staff who in turn were staring at her. No one said a thing. Should the mother have been challenged? Was it the shoppers/staff’s responsibility to do so?
