Teller pretended to scan my WRewards card

I went to the FoodMarket to purchase one item, and I had my WRewards card with me. The till operator Mahlatsi Phasha didn't ask for my WRewards card but I handed it in to her anyway. She PRETENDED to scan the card and seemingly she had scanned my item prior to scanning the card. I am shocked at how ********* she was by pretending she was scanning the my card. I get home and realize that the card was in actual fact not scanned, as per my till slip. The least she could have done was to say she had already scanned the item when I handed her the WRewards card, by no, she can fool a customer and get away with it, or so she thought!
