Fugate has what he describes as a “Waffle House” theory of emergency management to assess how bad a situation is after a disaster. “If the Waffle House is open and serving food and has got a full menu, then it’s green,” he said during an interview inside a FEMA mobile home parked outside a fire station in Joplin. “If the Waffle House is open but has a limited menu, it’s yellow, and if the Waffle House isn’t open, that’s red.” (Joplin’s local Waffle House survived.)
