CFA is a privately-owned company, so they have a different perspective on things relative to your run of the mill corporation. The founder had some peculiarities, no doubt, according to his little bio I read years back. One of which was something like, "If I keep it private and own it, they can't fire me for doing it my way."
They expand at a much slower rate and are less willing to accept that some stores will not survive. From what I read, they do beau coup market and territory analysis above & beyond similar companies. There is some value placed on the franchisee and employees such that they do not want to place them in a losing situation from the get-go. I think that this has something to do with a lower store density than, say, Starbucks or suchlike. They would rather that an individual store have more business than squeeze out the last possible dollar from a territory. See per-store revenue of KFC vs CFA above.
The CFAs around here are mobbed for lunch. Funny thing is, if you do take-out or drive through, it doesn't take that much longer than other fast food at that time. Just more efficient. They cycle through PDQ.
Oh, and the chicken is very yummy.
