Bad service

I went to engen garage grasmere to fill petrol,I parked there without an attendant,they were pouring petrol to cars that came after me,I hooted and asked why is no one attending to me,they all pointed at each other,I then drove away,it happened yesterday 29 January 2020,I’m so disappointed,around 13:15,I drove with a light on until I poured petrol in Sebokeng
