There is a Dunkin Donuts near the town lines of Acton, Maynard, Concord, and Sudbury Massachusetts open 24 hours a day with all night complete police protection.
Reminds me of a Steven Wright joke...
“I went down to the 24-hour grocery. When I got there, the guy was locking the front door.
I said, 'Hey, the sign says you’re open 24 hours.
He said, 'Yes, but not in a row.”
