I once did a service call on an ATM up at Vandenberg Air Force Base, about a 16hr day of mostly driving for me.

The new manager showed me the problem, the security light didn't work, and hadn't as long as he'd been there (about a month).

No problem! I'd brought enough parts to practically rebuild the whole ATM....but there was power to the lampholder [Linked Image]

The old manager had been putting the bad light bulbs that he'd removed back in the package (A19 lamps---the old days).

I had to drive to the local Safeway, spend 99 cents for 2 new incandescent lamps as I hadn't brought any with me, and...well you get the picture. [Linked Image]

How many electricians does it take to screw in a lightbulb?? Just one, but it can be quite costly if he's on double time [Linked Image]
