Commercial rage

There's this commercial that's recently been showing on TV that I absolutely loathe. I have effectively blocked out what it's for but it opens with a man entering an elevator, thanking the woman who is already there for holding the doors and saying: "Nine, please." She does nothing, so he reaches to push the button himself, and she moves to block him. He tries again, she blocks him again, and it goes on and on like that with her always blocking his access to the buttons. The catchphrase is "Hate stopping?" I simply cannot watch it. I have to look away or I just feel myself getting angrier and angrier. There are other commercials I dislike (for instance, the one which implies that if a woman drinks OJ she will then dance around her kitchen like a stripper) but none quite as much as that one.

What's your most-hated commercial?
