At a previous job I was in a hybrid role and spent some time in the office, some time at client sites, and some time traveling or working from home. Despite this, I had managed to score a desk assignment and had my own space at the office. I had a company-assigned Mac with matching screens permanently mounted to my desk, and also had some personal accessories such as the white Mac keyboard and magic mouse.
Because the company had grown, there weren't actually enough desks for everyone but since most of us were hybrid, it was customary to just grab an empty desk while working from the office if you didn't have one assigned. Sometimes people were only there for a couple hours at a time, and sometimes they moved when the "owner" of the desk showed up, but mostly it worked out okay.
One morning when I got in to the office and started setting up at my desk, every one of my white accessories -- keyboard, mouse, desk -- were completely covered in orange Cheetos dust and greasy fingerprints.
So I spent the first hour of my day cleaning, which included popping keycaps, disassembling my mouse, and cursing prolifically. When I left for the day I took the additional step of moving my personal items (including the keyboard and mouse) into a desk drawer.
So I didn't think much of it until I come back to my desk the following week and find my keyboard and mouse back on my desk and once again, everything covered in orange dust and greasy fingerprints.
After that the offending party was identified and formally chastised by the office manager. And I started locking my desk.
