Threatened to beat me up

I was at the Mangalani filling station being helped when the cash in transit van arrived, the driver told me to move out of the way very rudely, I explained to him that I was still being helped , he became verbally abusive and threatened to beat me up , he was so loud that the whole service station was brought to a stand still. We understand how dangerous their job is but this was unacceptable and embarrassing ..... I moved out of the way eventually ....I don't know if that is the way they are trained , to have no respect for the public at all, I was very humiliated , and will be taking this matter with my lawyers
