This was very entertaining. Your humour is shining through again! I guess I'm a tad confused about the time or era in which this is set, as it seems pretty fantasy RPG, but then you mentioned the singing fish. This could definitely be explained in a longer story, though, so that's not really a criticism.

I did find the protagonist a bit too laidback about the arrow and the message. Unless this is a meta story and he's in an RPG, this isn't how I see someone reacting to this situation. It's much more how I would react in Skyrim or Oblivion when I'm waiting for the Dark Brotherhood to try and recruit me and then they show up. (So there's the genius if this is an RPG sort of story. If it's not, then maybe this reaction needs a bit of tweaking.)

I also found the bartender a bit too pushy, but he's not the worst long-term character, either. He could be very annoying, though, if not handled well.

Overall, nice work! You have so many things you could develop further! My favourite is your sci-fi humour one thus far, but I'm enjoying going through your gallery.
