I'm wasting time on MN working very hard on my next assignment in my husband's office and a lady comes in from a firm of decorators who are repainting all the windows in the university. She asks nicely for all the stuff around the windows to be moved so the painters can crack on when they've finished the ones further along. Fair enough.
Then she asks my husband to unlock the door in the corridor so they can get access to the remaining windows. Husband politely tells her no, because they don't have security clearance. She gets rather insistent and again he tells her that it's a high security area and only people with clearance are allowed in there. She then starts arguing with him on the basis that the maintenance department have authorised her team to paint all the windows and therefore he MUST let her in. He responds that she may well be authorised by the maintenance guys to go in, HOWEVER, he is authorised by the National Security Services to ensure she stays out.
She's stomped off now to report him to the maintenance manager
