My manager once swapped my coworker’s keyboard to say “FUMICHAL” or something like that on the keyboard.

It was many weeks before my manager had to point it out to him that he did that. Since my coworker was a touch typer he just never noticed. I think my boss thought that since he was Polish that maybe he’d look down once in a while, but nope.

I don’t think he ever changed it back because he just never thought it was worthwhile to do so.
