I was driving back from Cleveland to Jersey last night. I hit a terrible snarl of traffic just as it was starting to get dark.
The darkness, coupled with the lack of activity started to get to me, and I was feeling pretty drowsy. I tried calling people, but my service was dead in Pennsylvania.
Finally, I got out of the traffic, and pulled into the nearest rest area. I needed caffiene, badly. I run to the machine, hoping for a pepsi when I realize my smallest bill is a twenty. I start asking around, hoping someone has change, but no luck.

A guy approaches me. "Whatsamatter, boy?" he asks me. I ask him if he has change, but he doesn't. "How much yew need?" he asks. I explain that I just need a drink to keep me up. He opens his wallet and pulls out two bills. "Here," he says, "and use the change to get yerself a candy burr, kid."
I start thanking him, telling him that I just need something to pep me up for the rest of the trip, but he stops me with an upraised hand.

"I don't need no reason, boy. I see yew need help, that's enough fer me. Yew just drive safe, y'hear?"

I heard. With the sugar in my bloodstream I was ready to finish the trip...
