Three Points

1. Splenda. The entire concept. "Almost exactly like sugar!" Well, the only difference is that it's less sweet! Why not just buy friggin' sugar?
2. Self-righteous people. They think they're so much better than me, you, and everyone else. While in reality, their supposed "aid and righteousness" to the world is actually counter-productive, as it just gets more people pissed.
3. Servicepeople with terribly simple jobs, but still manage to screw things up. I ask the breadlady about one of the ingredients in their sandwiches, she admits to being illiterate. How'd she even get a job there? The McDonalds worker, who can't seem to process the fact that because I ask for a burger without tomatoes, she doesn't need to tell me that the burger I ordered comes tomatoless. Good Sweet Jesus!
