i rarely see people not move out of the way to let people out and the people waiting to get on to let the people out.

i do have two elevator annoyances though.
1. the "no, you first" gesture between men. Neither get on as they try to out-kind each other and then the doors start closing forcing both men to dive into the elevator. I don't know why we have to be so chivalrous at this moment when there is a time sensitive moment of the door closing. each elevator is different.

2. the person who slides his arm in on closing doors. it happens frequently and is the most entitled, "i'm important, i can't wait for any of the other elevators that will be here in less than 30 seconds." no one ever says anything either. It's the jerkiest of jerk moves. Just wait. if you are so late that you can't spare 30 seconds, the tardiness is on you. and you should adjust accordingly.
