What was your source for this? There are many lists like this online, with several different answers on each list. I was surprised Zaxby's is on here since it is a regional company. Also, it's spelled Chick-Fil-A.
My source would be other people and what they have to say about fast food. And I don't understand why you were surprised that Zaxby's was included in the quiz, considering that the restaurant is one of people's favorite place to get chicken products/produce as far as fast food goes. Also, I found online that Chik-Fil-A is the most popular spelling of the restaurant instead of Chick-Fil-A. I didn't want to make the quiz to hard.
