Oh YEAH, that is the only reason I am willing to do them - I request higher amounts and often don't get assigned but that is ok. I plan them around other jobs / tasks so my gas is paid for.
I do have an issue with how SLOW they are to review requests, half the time I have to cancel the request because my willingness to go the distance has now passed (and the due date has too). You would think that jobs that need to be done asap or by TODAY would get looked at.
I realize that higher PAD jobs would be chosen last - but it is obvious nobody is taking these jobs.
