OK, Fast forward to the part where they are at the "Truk Stop". Now when Harry spills the salt and Lloyd tells him "You spilled the salt, spilling the salt is very bad luck, quick toss some salt over your right shoulder". Then he sits the salt shaker down on the right side of Harry's plate, then in the next shot it is behind the plate. Unless the salt shaker has legs it didn't walk over behind Harry's plate by its self.
