In grad school (or at least at mine), grad students get desks in offices, usually three or four to an office. My office is on another floor from the rest of my advisor's students and the labs I work in, so he asked to move me to the empty spot in the office now occupied by his other two students, who both happen to be women. When I went to talk to the bureaucrats about getting me the key so I could move my shit, I was told "There's a reason that's a girls only office".
What the fuck? Everyone's an adult by a good margin. I asked the current occupants of the office and they had no idea, and said that there was a man with a desk in there less than two years ago. Fucking stupid.
