LOL, it's funny 'cause it's true! To the OP, if you guys are new to the studio type of work then I do not recommend the drummer try laying his tracks down in a vacuum, you guys need to be there to play along with him as scratch tracks if not keepers. Lock in as a band before you try overdubbing single parts. Maybe you already are doing this, but I got the impression from the OP that the drummer was laying down parts without the rest of the band. If the engineer is forcing the one instrument at a time then he's not a very good engineer and/or he has a studio not up to the task. Also, when recording I suggest you let the drummer be the drummer he is, if his playing has worked in the practice room it will work in the studio as long as the band is on the same vibe. It may not be great technical playing but it will be honest to where you all are at, and that generally makes a better record than futzing with timing grids in pro-tools in some misguided effort to sound like an atomic clock.
