Very bad attitude and threat of assault to my pers

I drove into this garage to pour fuel and since it was so packed,I managed to clear aside so another car could pass.When it came to my turn to pour fuel,he stop from a distance and asked me in a very loud tone what I wanted and when I told him fuel,he asked me to go turn the car because the tank was on the other side.I then opted to move forward so that the pump could reach my tank and he burst into a frenzy,point fingers at me and asking me to move else he will assault me.When I asked to speak to the supervisor,he said I could go to he'll.I asked him to be nice but he kept pointing his finger at me and throwing insults at me.Since my car was on red,I couldn't drive off and rather asked for another attendant who was not of much help either.I dint think I would ever go there ever again even if am stock or to any other shell garage.It's the worst customer service I have ever received in my life.this is because even the guy that claimed to be the supervisor was not helping.
