I used to find a good number of discount cards and snacks on my desk all the time at my last job before I retired. :-)
Then of course there's what I call the "Office Bitch". The one that does absolutely nothing but browse social media all day then complains that their PC is infected with a virus, and then goes as far as blaming IT for not fixing it because they're same ones who are also too busy to be around when their PC needs fixing.
