Half those labels were wrong by the time we got to the far end" is the part that gets me, because I read a thread on a telecom forum where a guy ran a test on a few hundred tagged cables and something like one in five didn't match the label. Paperwork is only as good as the last guy who touched it, and that guy may have been in a hurry. Toning takes a few extra minutes and saves you an hour of hunting later.

Ha, same thing happened to me with white vinegar on my shower head!

Got a truck and a dive gear hookup yet? Tenders get picked fast down there.
