Does someone in your building or office consistently fail to follow proper elevator procedures? Do they not make the effort to hold the door even after they see you coming and make eye contact? Do they stink up the Zen space of the elevator with their cellphone chatter?
Then you may need to contrive an elaborate comic ruse in order to force them to watch this video on elevator etiquette, perhaps by hacking into that little elevator television and making this play instead of celebrity weather updates.
Probably the best tip is to always adhere to the “LIFO” principle, or “Last in, first out.” This means the people by the door should go out first. There’s really no need or time for chivalry or “oh you go first,” “no you go first,” in an elevator.
