This was years ago. And I did try a note! It didn’t work.

I switched to standing-only at work about 10 years ago and it’s been great, except for a 2-year stretch where the cleaners in the building I worked in would somehow find a free desk chair and push it under my desk every. single. night. So every morning when I got to work there’d be an office chair sitting on my standing mat and I’d have to find somewhere to put it. I tried moving it far away, finding a chairless desk on the other side of the building, but somehow they kept finding me a chair I didn’t want and rolling it onto my mat. Eventually I got a little guest stool and would pull that over onto my mat when I left, and that worked as a decoy chair and kept them from adding a chair. Maybe this comic was about them.
