The hype surrounding Popeye’s Chicken Sandwich resulted in Popeye’s running out of buns and asking customers to bring their own, a customer suing the company because he couldn’t get a burger, customers storming Popeye’s with guns, a lethal fight over the chicken sandwich, and even a Popeye’s chicken sandwich inspired holiday sweater.

In August, fast-food rivals Chick-fil-A and Wendy’s joined in the chicken burger hype by starting a twitter-war over their respective chicken sandwiches. Chick-fil-A first had a dig at Popeye’s, tweeting: “Bun + Chicken + Pickles = all the [heart emoji] for the original.”

Popeye’s responded with: “…y’all good?” Wendy’s then mocked both companies, saying: “Y’all out here fighting about which of these fools has the second-best chicken sandwich.”

It seems as though the battle between the chains isn’t over, with Popeye’s trolling Chick-fil-A as recently as December, by seemingly trying to poach Chick-fil-A’s employees for Sunday shifts.

Now, it looks like the chicken-sandwich battle will continue through 2020, with McDonald’s testing a new chicken burger in Tennessee and Texas through January 26, before potentially launching nationwide. The love for the chicken sandwich has even gone international, with KFC locations in the UK introducing a vegan “chicken burger” to its permanent menu.

And now, Smashburger wants to “throw its hat into the ring” according to an emailed press release. Smashburger’s new Crispy Chicken Sandwich is 70 percent bigger than its original crispy chicken sandwich and is served with lettuce, tomato, and red onion.
