Cleaners

The cleaners at my job are an odd bunch. On one corner of my desk, I keep my name plate, business cards, and various signs stating policies and such. I like to keep that in a specific order. If I place it in that fashion, and the cleaners come that night, I will find them in a different order the next morning. However, if I leave it the way they put it, it won't be touched the next time they're around. What's even weirder is they never put it the same way twice, so I know they don't have a specific set-up that they like. It's like they know which way I prefer to set up my desk and purposely mess it up when they see it like that. Dicks.
