A standard computer keyboard has a couple of little fold-away legs along its rear edge that are used to tilt the keyboard slightly towards its user. Every night, the cleaner at my office folds down one of those legs, so that my keyboard will wobble the following morning. What's in it for her?
Even more puzzlingly, this used to happen when I worked for an entirely different company in a different country. I know it's not the same cleaner, following me. So it can only be part of an international conspiracy of cleaners. Must be.
The question is, do cleaners do this to everyone, or are they targetting me?
