People that don't understand elevator manners...
1) If you are the last person to enter by stoping the automatic doors from opening only to say "oh I thought this was going (insert wrong way)" and giggle like an idiot as you leave, the new mortal enemies that you have made in that small space are now conspiring ways to brutaly destroy that which you love most.
2) It is not only incredibly rude, but also highly inefficient to rush into an elevator before the mass of people inside try to exit. If you do this, you deserve and should be painfully gang-banged by those people with no lube.
3) An elevator full of strangers is no place to talk to your friend about how your cheating spouse gave you herpes. Strangers don't want to hear that shit and regret entering said elevator for fear of their health.
4) If you are riding alone, please save that wet fart of mexican chili you had for lunch until you make it to the bathroom. It is noticed by the next person that enters and they will ask the security guard to review film in order to find you. Once you are found and after several days of stalking, they will secretly break into your car and take a massive dump in your back seat.
5) And last, don't be that jackass that takes your kid to work and let's them push every button when others are present. It is because of people like you that others have no hope for our future.
