SIGNAGE?

As the wife and I sat aboard the Maid of the Forth yesterday afternoon, sipping our respective whiskies -- I believe they were Highland Park and Jura, though our sadly departed friends on the outbound trip were Glenmorangie and Bunnahabhain -- returning from out visit to Inchcolm, the one time home of Walter Bower as he wrote the Scotichronicon, I looked out at the unfortunately present oil tanker being filled from a pipeline that traveled here from five-hundred miles away in the North Sea -- or so the informational audio recording told us -- whereupon I saw this sign painted in extraordinarily large letters and could not help but wonder for whom, exactly, this sign was intended.
