I don't understand the attitude that when someone says 'No' when you try to sell them something, you get mad about it.
Because that's what this article is talking about. He tried to persuade someone to invest, and they didn't want to. And he got mad about it.
This article has made me wonder if the right approach is answering 'no' initially to see what the reaction will be. If it's a decent reaction, then say 'yes' if you want it. If the reaction is off-the-wall, the answer is now 'no' anyhow.
