Worse service ever and beside, I should able to pay in whichever way I am comfortable with

Shoprite cash an carry 1599 van Der Hoff road. Kindly assist Harry with customer service training or get out of the shop if he is not ready to work. We cannot be bul**** by him just because he had to work on the 31st. I went to purchase some few stuff using my bank card, a friend of mine asked me to pay for her items aswell and gave me cash, she required a separate slip. Walked to the till and asked the guy to separate the items them he further told me he is not gonna do that since it is possible to pay on both cash and card. I explained why I requested he started throwing tantrums telling me we enslaving them for no reason. The said items only costing R10. 00(reduced). He further took the items and put them aside, I then insisted on paying. So we ended up exchanging unpleasant words infront of customers and her manager/supervisor who Siad nothing. Whiles packing my stuff they continued talking ng about as if I am not there
