KFC

When my family was ordering KFC my mum asked the guy how much an extra piece of chicken was and he said $9.00 and then my mum said how come it says right here that any extra pieces of  chicken are $3.00 each. The guy just walked off and got our food he gave us the piece of extra chicken but he was holding it in his hands. We then asked to speak to his manager and he said no. We then walked out of KFC with our meal when we got home it was cold and disgusting, we then rang the manager and told about the guy and our food. He asked weather we could remember his name, which of course we couldn't because he was an asian and had we couldn't understand his voice or read the name on his shirt.
