People who take the disabled priority seats on the train when they are neither disabled or elderly, i.e teenagers and people too lazy to walk a few more steps into the train. People who speak loudly while on their phone in public. People who chew gum loudly. Religious folks who tell everyone how to live. Pricks who don't use an indicator while driving or sneak up and force their way in front of you when a lane ends. There are plenty more but these came to mind.
