For those wondering and not to distracted by Bill...
The sign, we believe, once said "HERSHEY'S BARS 2 for $2"
However, the first H, both E's and the second S (and possibly the apostrophe) fell off, while all the other letters in the first line were bunched together. The R was smooshed with the S so that, on initial glance, it looked like an FIS. It took us a moment to determine what it actually was trying to convey.
If it wasn't dark and rainy, I would have stopped and taken a picture,
