1. Whether you're entering or exiting, whoever's in front goes first. Move to the back to make room for more people.
2. If the car's crowded, ask someone to push the button for your floor.
3. Keep elevator conversations to simple greetings and comments. And don't talk business unless you and your coworker are alone between floors.
4. Put your cell-phone calls on hold until you get to your floor.
5. Resist the urge to preen in the mirror.
