THEM: how about you tell me what you want and let's see what we can do  YOU: i'd like the book and the balls.  THEM: i can't give you the book and in addition i would like one hat  YOU: that would leave me with 3. i don't want to get rejected. can you let me have the rest if you get the book?  THEM: you won't get rejected unless you have been making consistently crappy deals, but i will make that deal for you. i will take the book and give you the hats and balls  YOU: thanks.
