Kind of tech related:
Coworker had spent days trying to make replacement radio transmitter work. The receivers were all acting like they were expecting PL (sub-audible tone), but he was insistent that the old transmitter wasn't configured for PL. Boss sends me down. I read all the docs. I try *everything.* Days pass. No progress made. Boss finally arrives, pulls out service monitor, in a matter of seconds "Look, there's PL on the carrier, right there"
Apparently co-worker was looking in the wrong spot in the programming of the old transmitter and I just assumed he knew WTF he was talking about. Lesson learned.

Roommate/homeowner wants to tile his countertops. We measure everything carefully. Note down the sizes of each section in inches. Add them all up. OK, this tile is sold in square feet. No problem, just divide by 12...
We had a LOT of extra tile.
