Security took out a gun in public

Today outside shell garage in Mhlanga Durban near the taxi rank 09 May 2022 at 6:15 PM. a ND846 driver who was dark and short, almost knocked me whilst he was stopping to drop a lady off. I told him to watch out before he causes an accident and he stopped and came out of the car. He held his gun and started pointing at me with his finger saying I need to respect him. I ask him if he was going to shot me or what. He put his gun back and told me to be careful whom I **** off.
