No Cashback

I often tell people that the Beacon Bay branch is the best PnP in EL. Obviously it's not perfect but Thursday (18/01/2018) I was so disappointed with the cashier... We went to buy a few things and at the till I also needed R 10 cashback. The cashier informed us that she had no cash. Really? No cash? I went to the manager and mentioned it and all of a sudden the cashier had cash... It's no use that a retailer offers a service (cashback at till) but the cashiers are unwilling to enforce that service. The largest amount I've ever needed at a tillpoint has been R 500 but I've found that many cashiers say they have no money BEFORE they know how much I need... This was the first time I've had this problem at the Beacon Bay branch. But I'm even more disappointed because the cashier knew how much I wanted (R 10) but still said she had no cash. Such a small amount - what would happen if a customer needed a R 100?
