Let’s discuss an unwritten rule.  We have a revolving door at the entrance of our work tower.  This is great since you don’t have to feel obligated to hold the door for strangers.  An added bonus is that it's one less public item one has to touch, thus translating to the less chance you have of picking up some disgusting germs on your hands.

A revolving door is usually divided into three parts.  The one at work easily fits one person in each section and you can squeeze two people in one section if both walk carefully.  You see this a lot with coworkers or people who know each other and it speeds up the line if others are waiting.

There is an exception to this though.  If you’re a stranger, you are NOT allowed to share one of these sections with another stranger.  Yet here I was the other day entering the door at my normal pace and halfway through the three second experience I looked behind me and there was another guy in my space!  No one was behind him so it wasn’t like he was trying to minimize the wait for people behind him or something. 

Personal Space Alert – Intruder!  Intruder! 

I wish I had one of those annoying car alarms from the late 1980s that said things like “Warning, you are too close to the car.  Please step back.” But it would say something like “Warning, you are violating a stranger’s comfort zone for personal space.”

It’s one thing to be jammed up with people in an elevator – overcrowding there is expected at peak rush hour times.  But a revolving door does not have the same rules apply to it.  If you don’t know the person, wait the three seconds for the next partition of the door to become available.  Even for a "hurry up" person like me, it's not that long of a wait.
