Input: The other day I got a call from a client, he had a last minute gig and they needed two people at $XX/hr. Would I want to do it and did I know anyone else that would do it. I said I can do it and I will call around. I text my buddy (we'll call him Greg) who is in the same industry. I said "you free for a gig tomorrow evening? $XX/hr and they want 2 people." He says sure. Next night we show up and do the event, no issues. 

Later, I give Greg the client's email and tell him to send them his invoice directly. All of a sudden Greg gets mad, he apparently doesn't like said client and said he only did the gig as a favor to me, and wouldn't ever work with client and so now is demanding his full rate $XXX. He seems to think I tricked or misled him. Truthfully, I didn't know he had history with the client, nor did I know he was doing a special price just for me. I thought I was being nice by bringing him on, and I was upfront about the rate and commitment. In my mind there is no difference between me billing the client and then paying Greg versus just having Greg bill them directly. Greg feels he was taken advantage of.

So am I the asshole and how do I fix this? I don't want to lose a valuable industry connection but I also feel like Greg is being unprofessional and petty. And obviously I have to make the client happy too.
