Filled in last night in a band I used to be full time in. The bandleader/bass player injured his hand so couldn't play but was there running sound. Agreement was I get the regular cut + his cut for filling in on short notice. At 50 bucks a person it would have been a total of 100 dollars. I even heard him telling the drummer (who got the payout from the bar) this but the drummer ended up just giving me the 50 dollars that everyone else got and than pretty much avoided me the rest of the night. 50 bucks won't make or break me. It's the ethics of it that bother me. I'm tempted to bring it up to the band leadership but don't have any to sound petty.
