Half cup drink

I was just at kfc themba in hammanskraal, i ordered a meal for a friend and myself, first of all there's flies everywhere, aircon if off. Secondly if you order a meal and don't want ice with your drink then it comes half full, hence, I'm being "forced" to take my drink with ice. This is a ripoff. Now I was forced by manager Nurse that it's procedure and I either take it or leave it. What an awful restaurant.
