Disgusting service at Debonairs North riding

On the 31st December 2018 I was rudely turned away by the so called manager at Debonairs North riding for trying to buy my son a kiddies pizza with a R50 note. She said that she could not serve me because she does not have change for R50, I was rather shocked by this as surely it is her job to make sure she had change when they open. Not only was she rude to me and argumentative, she did not even have the decency to apologize or ask me if I was prepared to wait while she try to get change. I have never been treated this badly before or turned away in such a rude manner at a food outlet before. Needless to say I will not be visiting a Debonairs again anytime soon. I'm feeling disgusted and disappointed.
