I make a plan yesterday to work on my CFO's PC today during lunch. I see him around 10:30, and he tells me he will be heading out at 11:30, and will leave his door unlocked for me. I get to his office at 11:35, and the door is locked.

I check around, and find someone with a master key, but their key doesn't work. I check with maintenance, and he says the guy changed his lock recently, so only he has the key.

I guess I will be doing this tomorrow, instead. Way to go CFO.
