No Cash Back, Cashier Rude

This is BP PnP Brickfields, so this is the second time i went to this pick and pay and i am told that they dont do cash back or withdraws while paying for my groceries or not, there is no sigh at the door. when i asked why not? a very rude lady by the name of Virginia Sithole told me its the LAW. This was strange because i use Tyme Bank and its states on their website that i quote "Withdraw cash at all Pick n Pay and Boxer stores till points" besides that this is un accceptable and a huge inconvinience, i buy groceries at pick and pay because of their good quality foods and convinience, Pick N Pay should do more in monitoring stores in locations as the service is bad.. cashiers are rude. services are stopped for no reason. i will not recomend PnP moving forward.
