I have a friend who was sitting and watching a football game, when he got a call for someone selling “vitamins.”
He had nothing better to do, so he started chatting them up. He had soooo many questions! He would agree he needed them, get halfway through his credit card number, and then he would suddenly have another question! The guy would go ask his supervisor and come back with an answer, which led to another series of questions.
3 hours later they hung up on him.
