It depends -- if you are in a hurry, it's going to hurt you more than it hurts TSA, but otherwise, it probably bothers them more. I've never had more than a very brief delay, though. There's extra lulz for me because if I check a bag on a domestic flight it is essentially always because the bag contains a firearm. The red-tagged bags must fly with the passenger, and TSA has already had extended contact with me by that point (they search the bag containing the weapon in your presence, usually in a private room, etc.), so I think making me miss my flight at that point would cause them a lot of trouble without me even needing to prod.
