Chick-fil-A is known for its strict policy of always being closed on Sundays, but some north Texas locations opened their doors this Sunday to provide free food for people whose homes were ravaged by tornadoes that killed at least 11 over the weekend.

The Christian-owned restaurant chain remains closed on Sundays in order to encourage its employees to rest and worship as they choose. Chick-fil-A spokeswoman Amanda Hannah said the north Texas restaurants were not open to the public, but that employees were only there to prepare and distribute free food to emergency responders and others in the aftermath of the deadly storms.

Jared Guynes pointed out the company's generous act in a Facebook post, while encouraging others to "buy a chicken sandwich" to express their appreciation.

"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," Guyness posted to Facebook on Sunday.
