What is behind Chick-Fil-A's enormous success?

Is it the chicken? The customer service? Or something else?

Open only six days per week, Chick-Fil-A’s per store sales are outpacing the second best performing quick service…

The Forbes article about this massive success attributes it mainly to two factors: great food, and outstanding customer service. If you have been to Chick-Fil-A, then you already know that it kills it in these two areas. I have chuckled to myself when visiting other quick service restaurants and found them trying to capture the Chick-Fil-A magic by saying “my pleasure” when I thank them. Everyone knows Chick-Fil-A has mastered customer service, and everyone is trying to match them. But the magic isn’t in just saying “my pleasure.”
