A：Hi Chen Hao, you look upset. What's wrong?
A：Why couldn't you get off?
A：Sometimes people on elevators can be quite rude and treat others with sheer indifference. They don't seem to realize that the rules of manners apply to elevators as well.
A：To start with, if you had waited to get on the elevator, you would have been near the front and not had to push your way through the crowd to exit.
A：There's always another elevator.
A：When you got on, you should have stepped to the side near the door so you would be out of the way of others trying to follow.
A：You reminded me. I am planning to see the new media exhibit on the 20th floor this afternoon. Would you like to go with me?
A：At the least the man at the front of the elevator who was not getting off until the top floor was polite.
A：Another polite move when you are standing by the elevator panel is to figure out which buttons hold the doors open and which ones close them.
A：As an added courtesy, offer to push the appropriate floor for the people who can't reach the buttons.
A：One last thing...when the elevator arrives and the door opens, stand back. Give people room to exit. Besides if you don't, you could get run over.
A：Elevator etiquette is simple. Be considerate. If you will be exiting soon, stand near the door. If you will be one of the last to get off, stand near the back.
