My hubby told me something "wouldn't start" and I automatically asked him if he was sure it was plugged in. He gave me such a look. But half the time at work when someone would come to me with "it just won't turn on" the problem was that something wasn't plugged in.
Still happens. I couldn’t get a document scanned and kept turning the scanner on and off until I finally checked the usb cable which someone had accidentally pulled out.
I am quite capable of such looks. Wanna see one?
I used to do IT support back in the day. Our csr’s were large commercial users, but also included the the military in some circumstances. A repair man was sent out once to a large military base for a dead csu/dsu. He found that an enlisted tech had thrown the CSU’s O N / O F F switch to the OFF position thinking it stood for officer mode insomuch as they were sending encrypted data and he didn't have sufficient clearance. :~)
