Bad service from the petrol Attendant

What happen is My car was almost empty on fuel and i was doing my shopping in the mall and i parked my car next to Sasol aiming to fill up my tank when i come back as i normally fill up at the same garage and to cut the matter short i came back from my shopping and i reversed to fill up the tank of my car and i waited and all of a sudden heard 1 guy saying dont help him and as i was going out of my car to find out why im not getting the service while i came first i realised that my tyre is flat and i just pumped my tyre and left and on my way home i realised my tyre is leaking i had to used a spare tyre and i also replace my tyre i will never ever fill up at any sasol garage. I would understand if that parking lot had some sort of signage to it date was 30th of December 2017
