Rude Cashier - Consumer Complaint for PEP STORES

The Cashier (Khosi) from Pep Eyethu Mall Orange Farm was rude to me and the customer before me. She told the customer before me not to come before she says "next customer" because of she wants she can just leave her there. To me she said its my job to greet her, it was even merely a second of me arriving at the pay point and she already told me why I am not greeting her as I found her at the till. Her colleague, who was on the next paying point laughed and it was a joke to both of them. I felt like a fool and very humiliated when they both laughed, the colleague was very happy that Khosi is addressing me and telling me to greet her.
