Well the clue is in the name, I suppose.
Many many moons ago the band I was in in was offered the support slot for Martha and the Muffins, a sprightly young pop combo of some note in that era, top ten in the hit parade and all that. Great, we thought! A fee of £400 is mentioned. Even better, we thought!
"Ah, you misunderstand, my dears" says the promoter, adjusting his top hat and twirling one end of his moustache "YOU pay US the 400 clams or you aren't getting within 10 feet of that stage! And no, you can't use their drumkit!"
We didn't do the gig :-( although we would have done it for nothing.
