That's all so funny because it true! Another couple of the most annoying to me are:
The cell phone chatter... Shut up and take care of business!
The "happy pooper". It annoys the crap out of me (literally) to hear someone come in the restroom, humming and whistling. He sits down in the next stall, usually with a newspaper and gets to work like one of the seven dwarfs. Whistling and grunting, he's an obvious "out of the closet" pooper - "dum, de dum, dum", humming while he executes several blasting "jailbreaks" without the benefit of a courtesy flush or a camo-cough...
Disgusting, shut up already...
