How about the BR signing out one of the three electronics keys for themselves (of which we need all 3 on the floor) and simply leaving it magnetized at the top of the doorframe to the locked stockroom? Not visible unless you looked, but still out in the open. New electronics TL nearly had a brain aneurysm when they saw it. At first, they asked which of us had done it, and when confronted with the fact that we had our keys signed out and on our person, realizing that the one signed out simply to "BR" was the one left, nearly tore off the BRTL's head (who knew they were getting the key and leaving it around so they "didn't sacrifice speed waiting" on us) This is the screams at TMs in the back, CCA'd the ETL-AP BRTL I've mentioned before, who decided that his team waiting on Electronics or Photo to open the door was too much of a hassle, so he told his team to sign out a key and leave it where all of them could get to it (but not in the back, no, that would be too incriminating as if the signing out the key to BR wasn't.) Thankfully, this BRTL is now on very very thin ice once the STL and ETL-AP (who is very pleasant, until you piss her off) found out.
