and breaking shit in the process.
We had a sort of "complaint book" for the cleaners, it was full of "Avoid putting water into my keyboard", "The ball from my mouse is missing", "Do not unplug the building server", "Don't throw stuff on my desk into the garbage" and similar things.
In the end it was agreed that nothing shall be moved around on the desks and only free surfaces had to be cleaned. From then on everybody covered the last square centimeter on their desks with paper from then on. We did put weights on the paper so it didn't get accidentally be blown off.
Did I mention cheapest bidder?
