Now Isn't This Just Wrong

I am in the process of arguing with a client to prevent him from paying me. In order for him to pay me, this client wants to take out a loan from a bank, or even worse, a cash advance on a credit card that still has something on its limit, while the client is working unpaid while they go through a training period at a new job.

I mean, I want to get paid, but on the other hand, for the amount that this bill is, I can wait the additional 2 - 4 weeks until this client can pay.

Is this screwed up or what?
