I bought a book about sales. After reading the first few chapters, I think the title should have been "How To Lose Friends And Completely Repulse People".
The things they suggest you say to prospective clients are kind of sleazy and condescending. There are politicians convicted of sexual harassment who have better deliveries.
Admittedly sales is not my strong suit. Hence why I bought the book. But taking the perspective of a customer, if someone approached me this way, I think appropriate responses would include mace and a restraining order.
I am looking to add to my roster of clients, but I think there has to be a better approach than the one suggested by this book. You should be able to pitch your services without people wondering how many times you've been prosecuted.
