Yes


Ex Input:
THEM: can i have 1 of each thing.  YOU: sorry, i need 1 book, and at least 2 hats.  THEM: dang, i need 1 of each thing to even get a remotely decent score.

THEM: no deal  YOU: setting numbers to 0 and waiting for the no deal button  THEM: same here.  YOU: unless you can settle for me getting 1 book and 1 hat?
