This morning Chick-fil-A is breaking their own rule and cooking on a Sunday. For the best reason possible, to help feed those first responders and people in need affected by last night's tornadoes.

Yesterday, a Chick-fil-A restaurant in Rockwall, Texas, broke a company-wide policy about staying closed on Sundays in order to deliver food to first responders and people whose homes were destroyed by Saturday's deadly tornadoes.

Facebook user Jared Guynes posted Sunday morning that he saw employees inside the location, presumably restocking their truck to make runs.

Garrett Dobs confirmed in the comment thread that he works at that location and is "happy we stayed to do that."

Kevin Douglas of the Garland Fire Department gave his thanks in the comments: "A huge thank you to Chick-fil-a from the Garland FD!!!! The sandwiches have been awesome and kept us going. God bless y'all!!"

Jared's post went viral, garnering more than 85,000 likes.

Chick-fil-a has since responded, telling CNBC that no stores were open on Sunday, but employees "from various restaurants in the area did volunteer to prepare and distribute free food to responders and others affected by the tornadoes."
