People who get on the elevator before you can get off.
People who drive like maniacs, not signaling, cutting people off and so forth, and then they complain about other people doing the same thing.
People who get drunk and act like it is the first time they've ever had a drink in their life. Also, people that talk about how drunk they got "that one time".
People who don't tip. Me and a group of friends go out for wings every once in a while, and one guy will get his wings and a glass of water, while the rest of us get some cokes, or some beers. Make it worthwhile to the server. When we leave he pays the bill to the cent. The service is fantastic, he's just a cheap fuck. Makes me sick.
Parents that bring their crybaby kid to restaurants and other public places and let him whine and cry for 2 hours without doing anything.
People who beat their pets in public.
Going to a department store (Best Buy) and knowing more about the products then the sales staff.
I think that's all for now.
