Unhigenic chicken

I purchased half a chicken and a side salad at the drive thru. When I got home, I wanted to tuck in and have my meal. As I was eating my favorite chicken, I saw something. Guess what I found? A piece of someone's finger nail in the sauce on top of the chicken. What a disappointing experience, I couldn't eat further, had to throw the meal away. How disgusting and shameful. I'd I could give no stars, it would have been better. This is the first time that I experience something like this.
