I am guessing the guy behind Chick-Fil-A is a religious conservative owing to closing on Sundays so the real miracle is that they were able to beat out a California company when California's political bias will be more against religious groups. Trust in business has declined as companies latched onto fake Corporate Social Responsibility virtue signaling so honesty may be why Chick-Fil-A wins.
These surveys are meaningless. None of them are more successful than McDonald's, which has 18X the revenue of Burger King and 4X the revenue of Taco Bell, KFC and Pizza Hut combined. People vote with their wallets far differently than they do on surveys.
