THEM: hello. i'd like a book, a hat and a ball.  YOU: i have to have either the book and the hat or the book and all the balls  THEM: i can't give up the book. at the very least, i'd need the book and the hat, leaving you with three balls.  YOU: if you take the book, i need the rest  THEM: there's no way i can do that. i'd be left with 4.  YOU: unfortunately i think no deal  THEM: i don't think we'll be able to make a deal, either. i'm sorry.  YOU: no problem, no deal  THEM: ok. no deal.  YOU: no deal.
