"This Georgia-based, round-the-clock diner chain—beloved for its abundant Southern-style breakfast— temporarily closed 418 restaurants nationwide on March 25 in response to the coronavirus crisis, while roughly 1,574 locations remained open with many shifting to takeout. The chain is so rarely shuttered that its operational status serves as an informal disaster barometer used by FEMA, employing a three-level index that distinguishes full menu with power, limited menu often on generator power, and complete closure; former FEMA chief Craig Fugate has said that a closed location signals a severe emergency." - Jenny G.
