My boss from one of my current jobs referred me for a part time gig with a different organisation that he's with.

It would be really interesting, and I'd love to do it, but after doing some research into the company I get the feeling that it might not be a job so much as a volunteer gig with nominal payment. It's a community organisation, and they seem to have a pretty minimal budget.
I wish people would be clear about these things upfront; as the applicant I don't feel like I can bring up money at this point, and it ends up a waste of everyone's time.
Also, if I turn it down it's going to be super awkward with my boss.
