Wow, you just reminded me of something funny that happened about 15 years ago.

A younger friend of mine was interested in tech, and knew I was "good with computers". They had taken some online quiz, and said I should take it. So I took it, and filled out my info thinking I might win something (I was young, and didn't particularly care.) About 15 minutes later I got a phone call from a guy trying to tell me that I was in a dead end job, and that I would never be anything if I didn't go to the school he was pushing. I think I just laughed, and said something snarky like "at least I'm not calling people up selling things." Then about an hour later he called back from another number, and was making fun of my (admittedly awful) band, asking where he could buy tickets. I calmly just told him we would appreciate the support, and gave him our website. He just hung up in a huff, but it was a very weird exchange.

In any case, I am very surprised anybody ever buys anything from pushy salespeople. I always immediately equate it to a low quality product, or a business with questionable morals.
