I read a field manual from the Illinois State Archaeological Survey that says to write unit, level, and quadrant on the bag before you even start digging that level. Having the bags pre-labeled means you just drop the finds in and keep going, no stopping to write. It takes ten minutes at the start of the day but saves all that confusion later.

Right, because nothing says "I care about your safety" like zipping a lug nut on with 600 ft-lbs and calling it a day (the gun does all the thinking, clearly). I watched a guy at a shop near me run all five lugs down with the impact, no socket back-off, no nothing, and then act shocked when the customer came back with a wobble. The best part is these same guys will swear up and down their gun "stops at the right torque" (sure it does, buddy). Twenty extra seconds with a torque wrench versus a comeback and a pissed off customer, seems like a pretty easy math problem to me.
