Yeah 9 times out of 10 I'd rather go to Popeyes. It is greasy but it's spiced well and I can't think of a single bland thing on their menu.
I'll say though that the customer experience at Chick-fil-a is top notch, and they really have drive through down to a science. Buying the food their has always been a pleasant experience.
They employ 3-4 people to man their drive through. No wonder it's such a great experience. Subconsciously, I think I pick CFA over alternatives, in part, to not have to deal with poor customer service.
