Disrespecfull

Saturday morning (31/10/15) at approximately 08H10 I was filling my vehicle as normally at this particular station due to excellent service I always get from all the stuff.I asked the petrol assistant (nice guy) if I can pay inside the shop with my card because I want to buy something as well. He said I must get my stuff and the till will give me a slip.I can come to him and he will ad up with the R500.00 diesel. I did as requested with no problem. He gave me the slips and I was on my way very happy as always. As I drove out I heard shouting. As I looked I see they were shouting at me saying I have to come back because I did not pay at all and need to pay etc. I turned around and went back. It was a Embarrassment. I went to the guy that I paid everything at (guy with a hearing aid in left ear) and he went straight to \Jenette"(name may differ in spelling and pronouncing). She just waved and gestured with hand I can go. No apology no nothing for instigating that the hole service station and clients there saw me as someone that wanted to drive away without paying. This is very unprofessional. I hope you deal with this matter and that she gets to learn how to apologize correctly"""
