It is entirely possible that the drummer is right in this case; the band does owe him/her just for showing up. In this area (and I am told in many areas) drummers, regardless of talent/skill, are few and far between. That being the case, yeah, you should consider yourself lucky that the guy/girl bothered to show up.
The other side of course is that for a relatively small cost, you can buy a drum machine that does exactly as it is told (programmed), doesn't do fills when you are trying to talk, and doesn't endlessly twirl drum sticks. The volume can even be set by the band...
