Pathetic Service Renered

Every morning I drive past the Pick & Pay Express, Hans Strydom, Linden, Johannesburg. This morning we decided to grab breakfast from the Express Hans Strydom - biggest regret ever. It all started with the lady at the breakfast nook not grasping our order - we ordered the pie special which entailed a large pie and energy drink. I proceeded to the pay point and paid. In the meantime my friend was buying two Tinkies. We noticed when getting back into the vehicle, Susan (the aggressive and rude cashier), also charged my friend for the energy drinks. We went back into the express shop and explained the matter to the lady at the breakfast nook seeing that there were a long que at the pay point. The lady then escorted us to the till point. She tried to explain to the cashier, Susan, what the problem was, but Susan was extremely dismissive and aggressive. In fact it came across as if she was blaming us for the problem. She refused to just listen to her colleague and my friend trying to explain to Susan in her native language what the problem was. In fact, she screamed and simply refused to listen. I tried to intervene but she completely dismissed me, kept on acting and speaking in a very aggressive manor. By the third attempt trying to address her and her still dismissing me, I decided to go back to my vehicle to return the goods. No one deserves to be treated like that, being constantly dismissed in a very aggressive manor. In the meantime with all of this going on, there was a gentleman on my left hand side waiting for service, there was another cashier, but she was just doing her own thing - I actually requested that he should be assisted. I am sure there must be camara footage in the store. I then asked for the Manager, to my dismay, he was in the same area, but did not intervene by any means, so I am not sure if this is just the accepted manor in which their customers are treated or if staff are just simply afraid to address Susan. He did however listened and apologized. I must admit, in general, I don't prefer making use of Pick & Pay, seeing that I tend to receive much better service and treatment from Checkers staff, who are always friendly, helpful and have the skill to listen. Pathetic, most unacceptable treatment indeed.
