Here's one that I never would have thought of had I not been in the store when the guy came in.
Was present in the local Walmart the night that a guy with a suicide-by-cop wish came in. He was carrying, had already been on the phone with Maine State Police. He told them that he was going to enter and start shooting people and the police were going to have to stop him. He entered in one door and the employees started a rush of patrons out the other.
I was there with the family in tow. He had parked at the door that we went out and then walked to the other. Had he come in where he parked, that night would have had an entirely different outcome.
