Origin of Kaempffer's Korner

We journalists love our alliteration.
But if anyone out there is about 60 years or older and lived in Freehold, NJ, you might now that that Kaempffer's Korner is a rip off. My dad and Uncle Charlie ran an old produce stand on Route 9 back in the 1950s. (You know the lyrics, "Sprung from cages on Highway 9." The Springsteen song)
I think that's right, about Route 9, but I might be making that up. I'll have to ask my dad.
