Chick-fil-A employees in Lawton, Oklahoma, learned sign language to help celebrate a co-worker in a special way on Thursday for his birthday.

The fast food chain's local Facebook page shared a video of the team members singing and signing "Happy Birthday" to James, an employee who has hearing loss.

A co-worker brought James into the main area of the kitchen where he stood confused until his fellow team members began the song.

James was visibly overcome with appreciation and signed "Thank you" to the group as they applauded him and shared the special moment.

“It was inspiring to see the team come together to learn how to sign the Happy Birthday song to surprise James," Jonathan Pickett, owner/operator at Cache Road Chick-fil-A, where the singalong happened, said.

He added: "As you can imagine, it meant a lot to him. This type of selflessness is in Chick-fil-A’s DNA. Yesterday we celebrated James. Tomorrow it will be someone else. If not at our location, at one of the more than 2,100 Chick-fil-As across the U.S.”
