So I really enjoy being in the band I'm in. We're not famous at all or earn any money by any means. We usually perform for the fun of it and to get our name out there. It's just a good time, really.
Anyway.. we sorta have a schedule for when we practice and we all used to follow it. But for a few months now a member has been suspiciously sick everytime we are supposed to practice. It has now been over a month since we practiced last. And I'm slowly but steadily getting more and more annoyed by the fact that we pay for a room to practice in, but don't use. 
I have no problem paying if we use it regularly, like we used to, but I don't want to waste money on something I don't use. I simply can't afford to do that.

WIBTA for simply refusing to pay next time rent is due unless we start practicing regularly again?
