I'm in a band where we are supposed to practice twice a week but the drummer always has a reason he doesn't show up. The last few weeks it was snow (even though it really wasn't that much), before that he was sick.. He had a valid one too like his wife went to the hospital but he also had a seriously lame one. Someone at his work couldn't go to work so he had to fill in for him!... Does anyone have advice for this kind of situation?.. I'm not the founder of the band so I can't really say "Come to practice or you're out".
