I had a terrible experience with one of cashiers there her name is Lungile Ngubane she has a stinking attitude, so I get to the till to pay for the items that I had purchased . She asks me for the savings card of which I reply I do not have it . She then proceeds to say that I should borrow on cause they require it , I'm confused cause I didn't ask for discount or anything I just wanted to pay and leave. I turn around and ask the gentleman behind me if he has one , he says no . I then tell Lungile again that I don't have a card , she continues to respond with the same attitude that a card is required, I than got annoyed and asked her to process my purchase as I didn't understand why she was insisting that I get a card. She than gives me my change more like throw it . I have never experienced such disgusting service
