Who was watching everything going on at the Fishermen's Rest?

I think this would be the proprietor Mr. Jellyband. He seemed a fixture in his establishment. "Mr. Jellyband, landlord of "The Fisherman's Rest," as his father had before him, aye, and his grandfather and great-grandfather too, for that matter....all became acquainted with Mr. Jellyband, his French wines and his home-brewed ales. "
