Bad service all round

Yesterday I went to FoMiss in ormonde to our petrol. I parked and the petrol attendant didn't greet me, so I went on and requested R100 petrol and my tyres be pumped to 220. The attended then went on his business, and returns to my window I hand him the R100, he then says did i say R300 or R100. So i respond and say well look whats in your hand, to which he response \eish"Iook at the meter and indeed it was R300"
