Love Waffle House and have eaten there for years. Interestingly enough there is actually a Waffle House Hurricane Grading system. The claim is they are opened in all but the absolute worst of storms. Someone actually surveys all the Waffle Houses in the effected area and then declares the severity of the storm based on the percentage of sites closed.
My husband used to manage a Waffle House, about 10 years ago. We joked that when the zombie apocalypse happened, he'd still have to go to work. Awful job, celebrated when he finally got fired. The only time that the door was locked in the 3 years he worked there was after a robbery.
After getting fired from said Waffle House job, DH swore that he'd never set foot in one again. The kids and I eat there maybe once a year if we are traveling without him. Food is ok, like others have said very greasy. I HATE their coffee.
If you are ever in one and can watch the cooking area, note their marking system for keeping track of orders. Everything they put on a plate (ketchup, mayonnaise packet, knife, fork, slice of cheese etc) means something. That's how they keep track of so many orders at once.
His store was in a decent location so he never had a lot of trouble with customers. Employees were a different matter, all of the fights were among employees, one of them robbed the store while working night shift. Took $600 out of the cash register , took off with the waitress working with him, then sent DH "taunting" text messages for the next 2 days about how rich they were. Right up until they were picked up by the police in a parking lot where they'd gotten stranded because they'd spent it all and couldn't buy gas.
