More then likely the truth. I had the sad experience of working for a union company. I needed one of those little file box things put up outside my office for my mail.
I was told that it would take two weeks for maintenance to get around to it. I said fine I would put it up myself and asked for a drill. My boss nearly fainted. It seems it said in their contract that only maintenance was allowed to make holes in the building walls. I said fine what if I could get it to stay on the wall without making any holes in the wall. Would that be OK? He said that he guessed so.
They will never get that box off the wall. I used enough super glue to hold a house together.

That will take a prybar and a repair job on the surface that it was attached to.
Arm & Hammer and Super Glue make an almost inseparable compound. Cheap too.
