There is a big difference between leaving your rubbish behind for others to take away which is unacceptable and the reasonable expectation that your office be a clean, healthy and pleasant place to work. If the marketing people, the accountants, the MD or in fact any other person who works on the ground found their office with weeks of dust coating every surface and YEARS of dust, muck and grime in the corners and recesses they would quite rightly be appalled and want something done about it. Can't see anything prima donna like about wanting your office cleaned once in a while, why should it be different because it's an aircraft.
