Checkers Gezina appalling service

After making some shopping at checkers I thought let me get a sim card for my business, sim cards were placed next to the teller and I grabbed one so to pay when I pay for my groceries, only to be humiliated by a gentleman on teller 3, he told me I can't pay for the sim and had to go to the money market queue to purchase the sim. He said it was not his problem how I was going to pay it but that was my problem. He advised that it was the management who put it there and I must ask them not him. As he does not care. However a person of a different race was treated with respect and there were smiles from the gentleman. I'd checkers teaches its employees to treat people like trash I will be posting all these on social media. I once had respect for the retail shop and only used them but after today.
