Pathetic experience with Alexandra Shoprite

Today I had an unpleasant experience with Shoprite Alexandra after being assisted by a rude person by the name of Noyise Nojola who told me I must never buy savings stamps on deposit till ever again. She kept on going on that they just got back from lunch only cash is allowed not cards, and I must never buy stamps on such tills. Shoprite must get rid of such she's so rude
