KFC Serving expired drinks

KFC in Sea Point served me an expired bottle of coke with my meal. The bottle expired before 03 November and they gave me on the 21 November, the male server laughed when I went to ask for an exchange, there was no empathy nor apology. I’m disgusted with their service and won’t be coming back. As a visitor in the city, I’m disgusted. The treatment would have been handled better if I was white.
