KFC selling left over chicken from previous day.

A colleague and I each bought a street wise 2 from KFC on Durban Road in Bellville. When we ate it the chicken skin was not crispy at all and was very fatty and sloppy, the chicken had a funny taste and was grey in colour. It was a waste of money and due to the fact that i have heard stories of KFC staff sabotaging food when something gets replaced we decided rather not to take it back for a replacement and instead threw it away. I was a loyal customer to this branch but now after being served old chicken that was the last time they get my money.
