What Would You Do?

It's lunch time and you go to your favorite fast food place to grab a quick bite. Today your going to dine in and as you finally remove all of your food from your tray and get settled in at your table you hear the sound of a screaming child throwing a tantrum. You look over your right shoulder and in the middle of the dining section sits a mother, grandmother and a screaming child. You can't help but watch the mother try to console the child without success. He keeps screaming this loud piercing scream. You look around and everyone is staring at this same situation.
