Chick-fil-A hit $23.9 billion in sales while closed every Sunday. Its CEO explains why that won’t change, even if it costs the chain billions

Chick-fil-A has been closed on Sundays for 80 years, and its CEO says he has never even run the numbers on changing that.

“I never have,” Andrew Cathy told NBC’s Today coanchor Craig Melvin in an Oct. 14 interview for the network’s “Business in America” series, when asked whether he’d ever calculated the sales the chain gives up by staying dark one day a week. “And that’s being truthfully honest with you, I never have because it’s never something that we’re entertaining. It’s just too important for us.”
