The pimp (Jonas) has a client in mind for you. However there is no bargaining of commission.

You'll do this one for me. ALL for me. To see if you're worth it, then we'll discuss commission

Jonas laughs at your offer of a common pool of money for the girls. (there isnt one at the table at the moment)

Let the girls manage their own money? How stupid would that be? Those crack whores would blow it up their nose in an instant. I provide at least some stability for them.
Now are you going to take my most generous offer...or have I been wasting my time...and I dont like having my time wasted
