I noticed something about elevator etiquette the other day. I've been taking the elevator at my office more often recently while I recover from my blood clot.
In this case, I was waiting for the elevator with another gentleman. When the doors opened, it happened that I was the first one through. And, without even thinking about it, I took on the role of "driver" and the other fellow the role of "passenger."
"Second floor, please"
I punch the button for two; then for three, where my office is found. After some bumps and whirring and disturbingly clanky sounds, the doors slide open to the second floor.
"There you go. Have a good day, now"
"Thank you. You have a good day, too."
He steps out and I punch the button to close the doors and continue up the building.
Now that I know what to watch for, I've noticed this behavior on other elevator rides. Those there first almost always take responsibility for transporting any newcomers. When elevator passengers violate this rule, either by not offering to "drive," or by leaning past the driver to push their own buttons, the atmosphere gets ever so slightly tense, though no one is entirely sure why.
