Scott,
while I agree in principle, fact is.. if we negotiated for what we believe we are worth, we'd end up playing twice a year or regularly for peanuts...
So, to keep playing, we have to take the 'good' jobs with the others.... that means we check with management on the tip jar. Maybe a 5-piece band should have different set of guidelines than the solo player. You may play quite happily for what we have split 5 ways
