Things That Annoy Me:

* People who do not move back into the elevator when people are getting on, when clearly there is room behind them.
* People who do not allow you to get out of the revolving door first before attempting to jump in.
* People who do not thank you when you've held a door open for them.
* Stinky Lunch Girl: eating her foul, curry/maple syrup-smelling concoction.
