I have an obsessive-complusive person at my workplace who is known to 'tidy up' after people, even if they are only gone to the loo. Since I am a fairly tidy person, I do hate it when I come back after 10 minutes and find that my things have been rearranged and even that the lights over my station were turned off.
I'm not anybody's relaxation toy for God's sake and I won't crumple under anybody's control issues so I did my best to scare the person enough so as to give me a wide berth. Then she proceeded with writing notes full of rather manic rules and regulations, which I - and everybody else, as a matter of fact - happily ignores. Mind, the woman is not a health and safety officer and she works under me, actually, but since when have I been able to manage people? I really don't want to see what the next stage might be. She looks and acts paranoid enough to jump on my throat next time I place a pen out of line with the others.
But I digress, yes, I do hate when people rearrange my things, I like to have them in my own way, thanks a bunch.
