What's your pet peeve?

[724Skinsfan]

Have you ever worked with someone that you disliked so much that everything they do becomes a pet peeve of yours? Here's a small list (and yes, they are real)...

1) Plotting to leave work early because "the boss ain't here".
2) Asking customers to write in a letter of appreciation on their behalf.
3) Asking customers to send them some sort of token (shirt, mug, etc).
4) Boasting about doing your job...that's it, just doing what you're paid to do.
5) Laughing out loud uncontrollably right outside your cubicle.
6) Complaining about working over ten minutes.
7) Boasting about being the first one in every morning.
8) Loudly bitching out your wife on the phone.
9) Complaining about not having enough money to pay bills and yet seem to have enough to purchase an XBox 360.
10) Always having an excuse about why it's not your fault.
