I dislike telesales people who won't stop talking when you say you don't want to buy XYZ.
    But as I don't really hate them I put the phone down in front of the speakers, and let them listen to whatever folk CD happens to be on...
And I get annoyed at people talking on a subject, whilst assuming prior knowledge of vital facts, realising you don't know said facts, and then saying " I thought you knew that" and still not expaining it.

And to those people who complain about gas prices. Come to Britan, $6 a gallon, learn to hate!
