NutLoose has hit the nail on the head, I think. Some EngOs were impossible to get out of their offices, which was fine if you needed something signing, at least you knew where to find them. Others took the time to see how things were going out in the wind and rain; those are the ones I remember in a positive light.
All of the above applies equally to WOs, Flt Sgts, and other SNCOs too, mind you...
