Service very slow, unfriendly staff

Around 11.45 I was on my way home Lyndhurst, coming from Lanseria passed north riding Chicken Licken, I love hot wings very much, however after what I went through, I doubt I will ever eat them any anymore. First of all, I waited on the so called Fly Through (Drive through) for over 15 minutes to get to the window, I placed my order, 12 hot wings and medium chips for my daughter as she can't eat chill stuff, they are very slow and the order lady does not even smile, I got my order and it was R55 I gave the lady R100 and she gave me change for R25 short by R20..I didn't notice that until I got to a garage to pour Petrol, I am just advising people to always check your change they are clever people out there and I never thought it will happen to me. After taking my order as I left my daughter asked for her chips and only to find out there were no chips on my order, I made a u turn as I was still around, she gave me my chips, I then drove off...as I went into the N1 highway it was easy for me to start eating my wings, it was so hurting after all that experience now I had wings that tasted very bad like as if they were off eish. I only ate two and the rest threw them away. Bad taste.
