Bad service Maropeng

This morning I went Spar in boulders next to taxi rand 31 north road, Midrand. I received worse service from lady called Maropeng, she refused to assisted me simply because I had R100 and she didnt want with change i saw in her till. Even after telling her i saw change she still refused untill i mentioned Hellopeter. She then told me that i can go agead and complain because God is with her always... SPAR TRAIN THIS LADY SHES TOO *********** SHES DOES VALUE HER JOB AND CUSTOMERS SHAME!!!
