It doesn't take much for that to become "TIL Waffle House's owners are so greedy they force their employees to work even during a natural disaster when other businesses are closed". No it's pretty obvious why Waffle House would want to stay far away from this sort of publicity and have very tight control on anything said about it, especially if that publicity looks like it comes from them or is in any way endorsed by them.
Except for the long list of stories that have detailed how they actually do this - they have special disaster teams that fly or drive in for the purpose. And where do all the power and other utility linemen eat between their triple-pay shifts in a disaster area? At Waffle House, because it’s always open.
