Poor service, poorly trained employees, unhygienic practices

Chicken licken Bram Fischer (Kensington B). I went to this chicken licken during lunch, after driving back to work I realised I was given the wrong order (2 pieces of chicken instead of 8 hot wings with my meal 8). After I drove back from work to the shop to return the order, the lady handing out the order simply took back the meat, replaced it with the wings and placed it on the table in front of me. She did not even look at me she did not even apologise. When I asked her if she isn’t going to offer me an apology, she only mentioned that I had taken a bite out of one of the pieces of chicken- meaning she was more concerned about reselling the chicken that had already left the shop- Is this chicken licken policy? Do you resell food that was incorrectly sold and has left the shop? What if I dropped the meat on the floor? What if I licked it all?. Is your staff not trained in customer service?
