Customers came to the Chick-fil-A on Lawrenceville Highway on Tuesday wearing spots, droopy ears and signs that read "Eat Mor Chikin."

It was all to earn their free breakfast, lunch or dinner entree as part of the restaurant's 15th annual Cow Appreciation Day. Customers who visited one of the restaurants' 2,400 locations across the U.S. were eligible until 7 p.m.

Some simply stained their white T-shirts with market, but Lawrenceville resident Jessica Segura came into the restaurant in a soft, fluffy onesie with black polkadots. Tuesday's "holiday" may not have been what she got the onesie for, but it perhaps paid for itself with free chicken.

"My sister had the onesie the whole time," Segura said. "She got it for Christmas, so I might as well (wear it)."
