Here is a funny video of what most of us authors experience when we do our rounds of booksignings. I don't like doing them alone any more because of what Parnell Hall went through ;-). Also, never sit beside Sherrilyn Kenyon (Low is near Kenyon) during one. Much as I love, LOVE, that woman, you'll end up doing nothing but exercising your smiling muscles.
Unless, of course, you're a Mega Author. Totally different then!
