Yep. It sucks. I do pretty much only fill-ins these days. I have a pretty high minimum (for this area anyway). But as soon as I do someone a favor and take a gig for $150, someone will call with a great opportunity to play with a bigger name for more cash. And I also keep my promises and show up and the gig I originally booked. Oh well. That's the roll of the dice. But like you said, it's nice that the phone is still ringing. Many aren't so lucky.
