Worked on a couple of them. Also worked on an Assembly hall. Big mistake there. Wasted nearly the entire day trying to be of "some help", but they had too many workers there. (when the call goes out that helpers are needed, say, Saturday, yippee, half the publishers show up so they can avoid field service.)
Felt under-utilized. Handing supplies to "real" contractors when they needed them. (I'm handy in most trades, some wiring, plumbing, drywall, painting, carpentry, etc.) Even was an apprentice bricklayer in my youth. But there I was with the nine year old boys waiting for some brother to ask me to hand him something. Sheeesh! Should of got coffee and an egg-salad sandwich at lunch time and beat it out of there.
Oh well, it's behind me now and a good chuckle at what an "obedient servant" I was.
