I ranted about my coworker trying to shoulder surf me last week.

Yesterday, he bought a mini Monster energy drink fridge and put it under his desk.

Me: "Oh cool. I don't have to go all the way to the kitchen to raid a fridge now :-P"
Him: "I'm gonna put a lock on it."
His Boss: "You know he teaches a lockpicking class at the hackerspace, right?"
Me: *headphones back on"
