In high school, I had a good friend who worked in the local KFC, besides getting a real bad case of acne from all the oil and grease they use. Fortunate for him, after he stopped working there, his face cleared up completely in three years with the help of a dermatologist.
Anyway, the chicken comes frozen in boxes. They let these boxes defrost near the ovens. And then the rats and roaches come at night.... Oh my. Not good. Not good at all. Yuk.
