See Waffle House. A restaurant characterized by cheap food and full of postal carriers, cops, and EMTs. They have jukeboxes full of crappy music, but serve massive meals to make up for it. Called Wa Ho because most of the letters on their signs are burnt out all the time.
Trey: Let's go to the Wa Ho. I'm starving!
Greg: No, I hate that place. The waitresses all call me "hon" and "sugar"!
