I had no idea that such a thing as a Pal’s Sudden Service existed, but apparently, they sell hamburgers, chili dogs, and sweet tea all over Tennessee.  I did not — alas — get a chance to eat at one of their establishments.  But the delightfully campy exterior of this specimen in Greeneville tickled my sense of Americana.  And when next I’m passing through the neighborhood, if I think I can stomach a dose of fast food, I might just stop.
