Dominos and Fazolis both take those surveys very seriously. I should know, I was the one responsible for making sure the phone system that took them was up, and that data was exported on time.
Places like Dominos thrive part because of marketing, but part because people like consistency. I’ve tried at least 20 different local places for pizza, and you never know what you’re going to get from night to night. Overcooked, undercooked, too much sauce, too little sauce, too much cheese, too little cheese… all those things change depending on who’s working that night. When you go to a national chain, even in another city, the product is much more consistent.
