I play the piano and my BIL's fiancee asked me a few weeks ago if I would play the processional for their wedding in September. It would be 2 songs. Normally I would charge a small fee for playing. However, future SIL is very young and naive and is already complaining on Facebook about how much money weddings cost (just today she posted that she wants someone to try wedding hairstyles on her for free because she's "spent enough money on wedding stuff already"...). Also, they are obviously family so that makes it a little different too.
So, I am down to 3 options: 1, tell her how much I charge for playing in weddings and see if she still wants me to play. 2, tell her that playing in her wedding will take the place of a wedding gift if she's okay with that. 3, say nothing and see if she brings it up at all (she probably won't). WWYD?
