RUDE CASHIER

I went to Pick n Pay Evaton Mall again today after my previous unpleasant experience. And today the cashier (Puleng Tukula) who was assisting me was beyond rude. She was angry because I wouldn't let her touch my bank card. I am very much confused by this. She refused to turn the speed point machine so I may proceed with my purchase and further threw my receipt as I completed the transaction at me while I packed my card back into my wallet. I need to understand why a cashier needs to handle my card for me when the speed point machine is more than capable of guiding me through a payment process. Or perhaps I looked too illiterate to can follow written instructions. I am very much disappointed by the behavior and attitude of the cashier at this particular Pick n Pay.
