Given the correct change - wow

I stay close to Shoprite Cosmo City and buy there almost everyday. Today l was shocked when l went there and l as given my change in full. I have come to know that with every purchase l make i get my change 10c, 50c, R1 or more short and have come to expect it. It has become normal but l was surprised today when l checked my change and it was to the last cent. Well done Shoprite, I wish there would be more days like this one.
