Chick-fil-A is handing out free food to customers on Tuesday, July 9, 2019.

But there's a catch: In order to get complimentary breakfast, lunch or dinner, customers have to dress like a cow. Chick-fil-A's calling it Cow Appreciation Day, part of its nearly 25-year campaign to convince customers to "Eat Mor Chikin."

Anyone dressed "udderly crazy," as the website notes, should be wearing a cow costume or some kind of cow apparel. It's a good time to break out that sweaty cow onesie you wore on Halloween. Or put black spots on a white tee. Maybe work in a cow bell to annoy the other customers? 

The freebie includes: an Egg White Grill or Chicken Biscuit at breakfast; or an Original Chicken Sandwich or Grilled Nuggets at lunch or dinner. If you love your nuggets fried, note that those aren't part of the complimentary chicken deal.

At the opening of a new Chick-fil-A in Addison in 2016, customers waited 24 hours to receive one Chick-fil-A meal per week for a year.

Chick-fil-A has a complicated past with LGBT issues. Texas Gov. Greg Abbott just signed a bill called (by some) the "Save Chick-fil-A" bill, which stops the government from taking action against a business for its contributions to religious groups, though some interpret it to mean it allows discrimination against people in the LGBT community. It's proof that in Texas, Chick-fil-A's practices outside of the kitchen are controversial.

In a poll to determine North Texas' favorite fast-food joint in 2014, Chick-fil-A made it all the way to the final round, then lost against Whataburger. In 2018, Chick-fil-A was the highest-rated fast-food chicken place in the U.S. by the American Customer Satisfaction Index.

Chick-fil-A's free entrees are available until 7 p.m. July 9, 2019. A press release calls it "Chick-fil-A's largest single-day customer appreciation event."
