[A man in Maryland was fatally stabbed over a Popeyes Chicken Sandwich.]

A week later, Chick-fil-A threw shade at the chain, writing on Twitter “all the ❤️ for the original.” Popeyes responded simply, writing “ … y’all good?” and so launched a social media fight seemingly crafted for the dog days of summer.

As Shake Shack, Wendy’s and other chains weighed in, lines grew at Popeyes restaurants across the country. Employees worked overtime as locations sold out of the sandwiches.

A supply intended to last three months ran out in just two weeks, The Wall Street Journal reported, and, on Aug. 27, Popeyes said on Twitter that the sandwich was sold out.

The item would be back soon, it said. And nearly 70 days later , it will make good on its promise.

Popeyes and its owner, Restaurant Brands International, have spent much of the ensuing time working to secure ingredients and negotiate prices with suppliers, hoping that the sandwich will also drive an international expansion, The Journal reported on Sunday.

Only time will tell whether that strategy will prove successful, but the sandwich appears to have already been a boon domestically.
