Bad Experience with Sasol Truck Driver at Sasol Petrol Station

I was at Sasol Swartgoud 30 mins ago and bought a coffee. Was in my car in a parking bay on phone. The Sasol fuel truck arrived. He drove up next to my vehicle and started hooting. He then came approx 1 meter from my window and started hooting again. I got out of car and told him its a parking area and that i was busy on my phone and would move when finished. He passed a few disgruntled comments and got out and had a cigarette. He sat opposite my car at the gas bottle area and smoked his cigarette. I showed him the sign that was inflammables. He got irritated , aggresive and swore at me telling me to '**** off'. This behavior from a staff member is not acceptable. I went inside sasol shop and the lady told me the manager was outside with the driver. The manager took sides with the driver and was not helpful at all. When i spoke to him he was not wearing a mask. I explained what happened and manager was not interested and told me i should have moved my car as the driver wanted to pass.
