Remember to keep calm

I was on a long line at 7:45 am today at the grocery store that opened at 8 for seniors only. A young man came from the parking lot and tried to cut in at the front of the line, but an old lady beat him back into the parking lot with her cane.
He returned and tried to cut in again but an old man punched him in the gut, then kicked him to the ground and rolled him away.
As he approached the line for the 3rd time he said, "If you don't let me unlock the door, you'll never get in there."
