Having to sit at a different desk every day or for a few weeks at a time is increasingly normal in offices, as the management tries to facilitate flexible working and foster more creative environments, etc etc. But, the one thing nobody talks about amid all the guff about dynamic workspaces is the business of having to deal with someone else's filth.
If you have your own keyboard and mouse at the same work station every day you can relax in the knowledge that it's only your own questionable sticky blotches on the mouse and only your own splashes of wasabi sauce smearing the space bar. But if you're having to jump on to any old desk every day your first five minutes at work will be spent inspecting those smears and addressing the situation with antibacterial wipes.
And we love being self-righteous about it, don't we? We like to flap a bit as we're disinfecting the mouse and make comments about other people's dirt and low standards, to make sure everyone in earshot understands that we don't approve, and to imply that we would never leave a work station in such a state – only to go on and scatter flakes of croissant in between the keys and conveniently have to 'rush off' at the end of the day without making time to clear them up.
