I'm a very impatient and intolerant person. Must come from my German and Austrian heritage but my list of pet peeves changes everyday. Some current irks off the top of my head are:

Those automatic faucets in bathrooms that give you water for three seconds and decide not to work anymore

Chinese drivers

Wiggers

Fat welfare moms who chain smoke while pushing their baby strollers and who feed their little kids coke and pepsi as a safe alternate

Large numbers of chinese college students who walk around sharing a permanent group hug and grinning like idiots

Rainy days -- used to love them, now they cost me money as I work outdoors

Washing dishes has always been pure hell for me. Washing someone else's dirty dishes is gross and wrong. I've been know to eat off foam plates for weeks at a time to avoid dishes.

Let's just say the chinese in general.

Pushy strippers who hound me for lapdances when I haven't even gotten a fucking beer yet.
