On Thursday, December, the seventh at approximately 6:30 in the evening at the pilot located in los hills, California. I was the next truck in line to fuel. As I was engaging to pull forward into the fuel island the owner of this company pulled into the wrong way on the scales and then did a 5.Turn to cut me off and get ahead of me to feel. I got out of my cab and approached him but remained on the opposite side of a large painted concrete pylon He asked him what he thought he was doing and if he owned this truck Stop. His reply was time is money. Oh well what are you going to do about it. I got my phone and went to the opposite side of his truck to take a picture of his DO. T-number and with the windshield wiper cleaning tool. In hand the man chased me back to The cab of my truck. I called the service desk of the truck stop and two employees came out and confronted him. He was belligerent and at first refused to leave until he was threatened with the police . This man truly operates his business in such a way that he needs to behave like this. And order to turn a profit. He could not possibly be trusted either on the public roads or with anybody's cargo.
