Except Waffle Houses don't typically coincide with your typical Tesla demographic, it will take education to teach how good a grilled chicken biscuit with a double order of hash browns topped actually is. They do have tons of real estate in rural areas that would be ideal (cheap) for placing charging stations.

I've seen maybe a dozen Tesla charging stations in Meijer (Michigan/midwestern mid-market grocery superstore) parking lots. Typically the cars are empty while charging, but will have already cycled through by the time you get groceries-- so I've always assumed the owners run in for some supplies or walk to a nearby restaurant.
