Never purchasing from KFC AGAIN!

Yesterday I went to Kfc Plattekloof to purchase a snack for my two sons and myself. We ended up ordering through the drive through and after receiving our order I opened the bag to check that the order was correct. I was quite shocked to see how the burgers were wrapped, it looked like the paper has just been scrunched around the burger but I thought ag whatever its just a wrapping. Then on opening the burger I was so disgusted to see that the burger had actually been bitten into. I could actually see the teeth marks of the person who had taken a bite. I immediately called the guy at the window back and showed him what I had found, I must have missed the joke cause he then proceeded to laugh and ask what the issue was. I immediately asked for the manager who apologised repeatedly and offered us free food but like I said to him, why on earth would I accept anything out of that kitchen after seeing what your staff do. I cant believe the type of service that fast food restaurants are offering nowadays its absolutely disgusting. Do they not realise without us as clients their stores would close down??? So disgusted that someone could think to place a half eaten burger in a clients bag!
