I recently left a project I played in for about 4 months. The band was disappointed when I left, but there were no hard feelings on a personal level, from what I gathered. Anyway, we only played one show, for which I was to be paid $50. However, I forgot to ask for it before our last practice, and I'm wondering if it would be bad form to call the drummer (who was given the money that evening) and ask him to mail me a check for the $50. Normally, I wouldn't be worried about it, but we played for about 3 1/2 hours, and I feel entitled to my share. I haven't played many paying gigs, so what should I do?
