Politeness goes viral.
The two men got into an argument, with the driver, William Sauro, 53, briefly getting out of his car. When Sauro went to drive away, he hit Alvarez with the vehicle, police say. Alvarez then allegedly pulled out a handgun and fired at least four shots at the car. One went through the windshield.
Another customer captured the end of the altercation on video, which shows a man advancing, gun drawn, toward the reversing car.
