Discription of Events: JKC Delivery was written on the driver side door of a white cargo van. License plate X74689. Sunday, August 6, at 4pm, Bay Ridge Brooklyn. Old man, white hair driving erratic. Honking and screaming. Comes on my right side and screams something at me. I don't acknowledge him. Then me and the car in front of me are turning left and he is behind me at the light and when light turns green, he tries to cut in front of me and the car ahead of me. Mind you it is a one lane block. Number 1, the guy should NOT be driving. And number 2, if he is driving he should not be driving as an employee of JKC Delivery. He is a HUGE LIABILITY to you. He acted so CRAZY that I thought he must be drinking. Fire him. He is NUTS. Then coincidentally, when I am on 3rd Avenue he passes me up on the other side and now he is on the cell phone. He should not be driving.
