Chick-fil-A is known for being closed on Sundays. It's a fact that every fan hates, complains about, but eventually accepts. There are exceptions to the rule, however, as a Colorado Chick-fil-A opened its doors and helped feed first responders after a deadly shooting on Sunday, December 31.

The shooting occurred at an apartment in Highlands Ranch, as a suspect shot hundreds of rounds at Colorado deputies, according to Bro Bible.

The gunman killed Douglas County Deputy Zackari Parrish, and wounded six others before being taken down by SWAT, according to Fox 31 Denver.

While a somber day for Coloradans, the Park Meadows Chick-fil-A tried to help by opening its doors and serving 400 chicken sandwiches to first responders.

You might remember that after the tragic Orlando night club shooting in 2016, Chick-fil-A employees went in to work Sunday and made sandwiches for people donating blood to the One Blood center.

Also, just last month, the Chick-fil-A inside Atlanta's Hartsfield-Jackson International Airport also opened on a Sunday, as a massive power outage hit the airport, leading them to hand out sandwiches to passengers.

So Chick-fil-A's Sunday closure policy isn't as strict as it seems, but it unfortunately takes terrible occurrences for them to open their doors.
