Chick-fil-A broke from tradition and opened on a Sunday — and there's an incredible backstory

  • Chick-fil-A is never open on Sundays. 
  • However, this Sunday, the chain sprang into action to prepare free meals for the thousands of passengers stranded after a power outage at Atlanta's Hartsfield-Jackson International.
  • Workers "immediately mobilized" after Atlanta's mayor called the company to ask for assistance.


Chick-fil-A broke one of its core rules and served fried chicken this Sunday. And, the fast-food chain had an incredible justification for doing so.  

On Sunday afternoon, Atlanta's Hartsfield-Jackson International — the world's busiest airport — lost power, causing more than 1,000 flights to be grounded. As hours went on without power being restored, the city of Atlanta turned to Chick-fil-A to help craft a solution.

When Potbelly opened in 1977, it was an antique shop. The young couple who ran it decided they wanted to serve lunch to their customers and the store evolved into a local lunch spot. In 1996, entrepreneur Bryant Keil bought Potbelly and turned it into a franchise; he stepped down as CEO in 2008 and is no longer involved.

Today, not only do all the Potbelly stores serve sandwiches and fresh cookies, but each location has its own potbelly stove

Headquarters: Champaign, Illinois

Value rank: 15

At Jimmy John's, customers can't get enough of the chain's signature subs and "freaky fast" delivery service. Jimmy John Liautaud opened the first shop back in 1983 to avoid pressure from his father to perform a stint in the Army. Papa Liautaud lent him $25,000, and if the restaurant turned a profit the first year he wouldn't have to enlist. Sure enough, the gourmet sub business took off and he slowly expanded across the country — it now has the most amount of franchises in our top 25 list.

Jimmy John's franchises commit to sustainability by partnering with suppliers who reach high standards of sustainable and ethical food practices. The chain also employs local businesses to build and maintain each JJ's store.

US sales in 2016: $758 million

Customer satisfaction rank: 6

Value rank: 17

In 1937, Krispy Kreme founder Vernon Rudolph used a recipe given to him by a New Orleans chef so that he could make and sell doughnuts to local grocery stores. As the fresh-baked donut smell wafted into the streets, customers began requesting to purchase the delicacies directly, so Rudolph cut a hole in the wall to open his first retail location.

In October 2015, the chain opened a new store in North Carolina which resembled a coffee shop, Business Insider reported. Six months later, it was bought by JAB, the parent company of coffee brands including Caribou Coffee, Peet's Coffee and Tea, and Keurig Green Mountain, for around $1.35 million.

US sales in 2016: $2.2 billion

Number of US locations: 806

Customer satisfaction rank: 17

Value rank: 11

Whataburger founder Harmon Dobson's goal was to create a burger so big that customers would have to use both hands to hold it. It would be so good that at first bite they would declare, "What a burger!" Thus, in 1950, Whataburger was born.

What started off as a burger stand, almost 70 years ago, now has 700 restaurants in the US. Although it lost out to In-N-Out Burger in Business Insider's taste comparison, it's still a favorite of many in the south.

1. In-N-Out Burger

Headquarters: Irvine, California

US sales in 2016: $807 million

Number of US restaurants: 325

Customer satisfaction rank: 1

Value rank: 1

In-N-Out Burger scores highest on customer satisfaction and value, making it the winner overall.

California's first drive-thru hamburger stand, In-N-Out Burger first opened in 1948. Nearly seven decades later, the menu remains simple, offering only five items. But loyal customers know that if they want to expand their options, they can order off the not-so-secret menu — it features items such as a protein style burger and grilled cheese.

In-N-Out can only be found on the West Coast, but there's a good reason for that. Since the chain prides itself on serving top-notch ingredients free of additives or preservatives, all stores must be within 300 miles of the distribution facilities. Sorry, East Coasters.

BACK TO SLIDE

Atlanta's mayor, Kasim Reed, called Chick-fil-A at around 10 p.m. and asked for assistance, company spokesperson Amanda Hannah said in an email to Business Insider.

Typically, Chick-fil-A is not open on Sunday, due to the founder's religious beliefs. However, this Sunday, Chick-fil-A employees "immediately mobilized," making sandwiches and delivering them to the emergency operations center to be distributed to stranded passengers. 

"It has been a very difficult day for thousands of travelers," Hannah said. "And while Chick-fil-A is always closed on Sunday, our restaurants open occasionally to serve communities in need." 

Hannah continued: "We do not make a profit but do what we can to offer comfort to people experiencing hardship."

People immediately celebrated the chicken chain's break from tradition.
