A cruise company (grandlucayan.com) calls with a recorded sales pitch. I've gotten this call several times (it always starts with a woman laughingly apologizing for a problem with her headset - a clever ploy to make it sound like a real human in spite of the robo call delay - to lower your guard I suppose). After several minutes of recorded sales pitch (you have to respond "yes" a few times to keep the spiel going), a human comes on with a ~20 minute pitch. After that, the supervisor comes on to close the sale (which is when I finally told them to remove my name from their call list).
