Bad service received from *********** staff

Mampho was a cashier on till nr 2. This is an express till which accepts a max of 10 items. This lady didn't look like she wanted to work today. She was so slow and didn't show any interest in assisting customers. A lady infront of us wanted to pay using a Sassa card but Mampho informed her she should withdraw cash first and the system doesn't accept those cards. She then sat there and waited for the customer to go and withdraw cash. What's worse is she doesn't inform the rest of us why the que is not moving, instead she sits and folds her arms. I then asked her why we not moving she gives us attitude and tells us we must wait for the other customer. This shop was full and the ques were long, but she said if we not happy we should go join another que. When told she is being rude and that's not how to speak to customers, she said that's not her problem. She refused to call the supervisor to cancel the transaction so that the rest of us can pay and go. She needs training on customer service. None of us sent her CV for her at the store, she chose it and now she better give the service needed.
