Elevator decorum. My office is on the 4th floor of a lecture hall. Stairs everywhere and a few times a week I'll take the stairs all the way up but obviously not every time or even usually. If work takes me to the other floors I'll almost always take the stairs. Anyway, almost every day I'm trying to get to my office on the 4th and I'll have to stop at every floor for someone going up or down one story, and no they are almost always able bodied. Dude, if you are on the 2nd floor and just need to go to the 3rd do everyone a favor, including yourself, and just take the damn stairs, it saves everyone else time and helps your own health,... but no, every damn day. I'm stopped on 2 for someone who will stop me again just to go to 3.
