Poor Cashier Service

We visited the Centurion branch today, and when we got to the till point, the lady who assisted us, was utterly rude. Even though we greeted her in a friendly manner, she didn't speak one word to us. Our purchase did not have a bar code, and when she had to go check, she had the rudest attitude. And to top it all off, she was chewing gum open-mouthed the entire time. We still greeted her in a friendly matter, when we left, and still no reply from the cashier. This was my first time visiting a Chamberlain's branch, and I think it will also be the last.
