In the MACC parking lot, this driver (white older male with short gray beard/driver) got into his truck which was parked appropriately next to my vehicle (blue 2006 Civic). I was in my driver seat. Upon opening his driver's door, he hit my passenger door quite hard. He did not even look in my direction. He continued into his seat, started the engine, and rolled his window down. I got out and said, "hey sir, what was that about? You hit my car with your door." His response was outstanding and brazen. He opened his truck door again and said (while hitting my car again), "that's what that's about!" I came on foot around to see my door for damage and took a photo of his license plate. I said, "sir, you can't just do that to someone's car and not stop to see if there's damage. It is not okay to do that!" He started backing out and yelled angrily at me, "go ahead and call the cops then b***h!" And he continued to drive off. This man needs to be flagged, as that is a sign of careless manner and angry behaviors not well contained. I do have a small dent and white paint on my passenger side door, white paint on the rear view mirror on the same side, and from the second opening of his door on my car, white scratches and his white paint on the fender above the back tire. I don't need higher insurance rates, but this is ridiculous. How a grown man can do damage to others' vehicles and be just fine is beyond me.
