Bad attitude

Today around 16h00 I went to Pick n Pay New Redruth in Alberton for their month end specials. I then selected some few items, when I'm at the till the lady said I took the wrong stuff which was simba products. She asked me to mixed them with niknaks and lays which I did, when I came back she said I took the wrong size - I decided to leave that stuff. Then their supervisor/manager called Bheki was so reluctant to void the the wrong items back, he told us he's still busy. I then told the lady at the till that I'm leaving everything and will go buy at Lemon tree, then he came to do what he's getting paid for. He displayed a very stinking attitude, worse from a man. He bahaved like he was doing me a Favour, forgetting that I came to buy.
