Unless you really like long surveys, don't bother with the survey on chicken fast food restaurants. KFC asks about every little detail about your last experience eating at one. Such as -- were the napkins brown or white? Was there a logo on the napkins, or not? Were the napkins in a bulk self-serve container or pre-packaged with a utensil? And did you fetch the napkins yourself or were they provided with the meal? There were ENDLESS questions about the food itself.
I acurately told the survey that the last time I ate chicken fast food was about two months ago. So how KFC, expected me to remember things like whether the mashed potatoes came in a styrofoam container or a plastic container, I don't know.
