I recently got together with a group of local dads to jam. All of us have families and full-time jobs, so the idea was to have a fun social outlet every now and then. We practiced once before the guitarist was offered to play a gig at a holiday market through a friend of his. We played a fun 2-hour gig outside, which we all intended to play for free. In the middle of the gig, the coordinator of the holiday market brought us a tipping bucket. At the end of the gig, the coordinator handed the guitarist $50 in payment for our services. The guitar player pocketed the bill. As I was coming back from packing up the car, I noticed the guitar player empty the tip jar into his wallet. This isn't about the money (it'd be comical to split it 5 ways), but more about the principle of sneakily taking the money. The jam is fun and it has been great to play with people again, so neither I nor any other dad is going to mention it. It just makes me think this guitarist thinks that we're doing this in his service rather than as a fun social outlet. Was this weird that he didn't mention anything (i.e. just even an empty gesture that he'd hold onto the money or put it in the beer fund), or was it justified not to even mention it?
