What annoys me isn't her shooing him off, but his portrayal in general (he's pretty much a caricature of a sleezy harasser) and the fact that he's around at all. We're going to see that the only event relevant to the plot as a whole is Shannon buying the pot. There is no reason at all for her to put this guy in, especially when she already devotes the rest of her book to having rapists as the villains (and that's not an exaggeration. The villains are a race of monsters that seem to exist only to kidnap and rape human women for pleasure).

Also, like I said, she later does flat-out say that her Fantasy Magical Love Interest is so much better than human men as a whole, because of things like, "He lets me take the lead during sex".
