...or "why wasting several thousand euros a day on external developers and consultants is ok, but spending money on soft, triple- or quadruple-layered toilet paper does not seem to be ok."
I really hate using toilet paper that is at most double-layered, it makes me feel uncomfortable, and it definitely reduces my productivity because of that. Dear managers, next time you pay EUR 2000 per day for an external project manager, think about buying some high-quality toilet paper to make your dump-taking developer crowd happy. It shouldn't cost a fortune.
