I really don’t understand the hard sell approach used by certain authors/vendors in aggressively trying to push their goods. Though you may be able to cajole me into forking over $$ for your book at the bookfair (I am a pushover, often), you sweating and awkwarding me into doing so will only guarantee that though I have your book inside my house now, I will never read it, and will likely think of you only often thereafter in a gross light, thus netting you perhaps one book sold but a whole trajectory made mushy. Come on. Relax. Be cool. Things go around. Invest in yourself. Not all sales happen at the point of purchase, and better things are friends.
On a side note, in one instance this past weekend at the Denver book fair when I was shown a book and didn’t buy it, the presenter told his friend passive-aggressively toward me, “Oh, check out HTMLGIANT… it’s a great site, if you like sex and hyperbole and death.” I think he thought it was an insult. I got it tattooed on my thigh.
This one never gets old:
