LEFT AT THE PETROL PUMP WITHOUT FILLING AFTER 9 PM

IT was 9.30pm 6 April I was travilling from Joburg to Stanger, 3 ladies with 3 kids youngest 2 years old. We stopped at the garage because we were driving with the reserve tank left with only 4km petrol. There was a taxi filling and a city golf car filling on the same pump. One lady I was travelling with asked from the lady at the garage shop to use the toilet and was told that there was no toiled, she must go behind the building and wee there. We waited to be helped for about 10 munites and no one pitched. The other cars we found at the filling station were filled and left. We went to knock at the window of the garage shop to have someon to fill the car but no one pitched. we looked around to get some help as the attendant has vanished no one pitched and all the pumps were then switched off. We shouted for help at the shop as one of the windows was open and could hear that there were people inside the shop, but no one pitched till about 10:00 pm we decided to drive on with our small petrol. We drove slowly till we reached greytown with 4km petrol a distance of more than 15km. We thank god that we riched Engen Greytown. What would have happen if our petrol got finished on the way?
