The Waffle House Index is used by the restaurant chain to track which restaurants are open and which are closed - but it's so much more than a list of operating restaurants. The federal government has traditionally used it to track community responsiveness after major storms. The wake of the COVID-19 coronavirus outbreak, Waffle House's operation center in Atlanta has activated the index, which as of Wednesday was showing over 400 restaurants closed across the country. Tonight we revisit our interview with Waffle House public relations director with Pat Warner, who joined us in January of 2019 to discuss the storm response capacity of the company.
