The sign post was meant to be a gag on Oda's part, nothing more. Do you realize how easily they could destroy that sign, or point it in a different direction? The FireTanks and Straw Hats are on good terms now, but that doesn't exactly mean that they're friends. Bege still has to put the safety of his crew first, and he's made it clear at several points that he doesn't ultimately care what happens to the Straw Hats.

As far as Katakuri's vision goes, remember guys, its a few SECONDS into the future, not hours. The "horrific future" that he foresaw was Big Mom's scream after seeing the photo, that's why he ordered Bege to shoot him dead right then and there.
