Funny Daylight Donuts story:

When my wife and I lived in Ponca City, Oklahoma, there was a Daylight Donuts shop downtown. It was only open from 3 to 4 AM.

My wife wandered in one morning about 3:30 AM and sat down at one of the tables; they acted like we were insane (but they did sell us some doughnuts, though they had no beverages).

It makes me think the place was a front for something and not an actual doughnut shop.
