Some stuff I've learned recently is as follows:
There is at least an unwritten policy of FEMA called the Waffle House index, which uses whether Waffle Houses in an area are open to determine the level of impact a disaster had on that area. The logic goes that since Waffle Houses are open 24 hours a day every day of the year, if one is closed then an area must be in pretty bad shape. Either the water's too high for the employees to reach it or the employees are all dead. In either case, the area around the Waffle House could use assistance.
