Tool of the day "honorable mention"....
Hotel receptionists who insist on putting the CA and FO in rooms right next to each other (bonus points if the rooms are adjoined only by a paper thin "suite" door).
To the Receptionists:
We spend 16 hours a day within 3 feet of each other.
Really, it's really, really okay if we're on different floors.
Really. It's okay.
