"Upon exiting an elevator, allow the woman/women to exit first, "
The elevator icebreaker I use is "OK everyone, please observe proper elevator behavior, eyes forward and no talking".
I've yet not to get a snicker.
I remember the late Mike Royko wrote a column years ago, when feminists first started attacking chivalrous manners. He argued that men should always allow women to exit the elevators first and go up the stairs first because it was not only good manners and a sign of respect, but it allowed the men to get a nice long look at the woman's derriere. See, good manners pay!
you forgot...."cell phones excepted..."
A lot you know... it's "eyes on the numbers and no talking on the elevator."
