When I'm playing something with strings on it, a drummer who shows up for a small bar casual with a Peart mega kit that takes up half the stage. And then either doesn't use more than a fraction of it, or does long 16th note rolls down all the toms every 4th bar (which "fills" usually take up 2 to 3 bars in any event).
Sitting in a audience listening/watching the drummer:
Cats with ubber expensive kits (including the folks with 25 Vault or Signature cymbals) who couldn't swing if you hung them in the wind. Most often commited sin, turning the left hand stick around to the butt end and then barely tapping the snare, usually a bit late. If you're going to turn the stick around, it would be because a hard rimshot isn't cutting though and you really need to wallop the drum. But there is a breed of cat with really draggy and tenative left hands that invariably are holding that one stick backwards.
Overplaying for the music. Blues or R&B gig where the drummer is smacking a cymbal every bar. Tish, tish, crash, tish, ad naseaum. Or rat-a-tat all night long. Maybe if they're an ELP tribute band. But I don't need to hear a fill in every other bar of Let's Stay Together. I've heard Thomas Pridgen play this stuff with some restraint, you should be able to as well.
Playing too loud for the venue. Driving the level of everything up. Some rock guitarists are guilty of this too, but at least there is a volume knob on the amp.
