I went to pick n pay liquor in pretoria Station Square and bought what I wanted so now Im about to pay. When I asked if I can pay with my RCS card she told me while chewing her gum proudly that I have to go make a copy of my RCS card by myself, that after queuing there so I have to go queue again to make a copy next door and pay for it and then come back to pick n pay to continue to finish off the transaction. I use my RCS card at the other pick n pay liquor branches and no one as ever made me go make a copy of my RCS card first. I ended up paying with my debit card before I told them thats madness really
