I've only put out fliers once, to announce the opening of the bar, I rely on word of mouth to spread the desire to others. There would be no such thing if they weren't alive, would there?"
He kept smiling. "You have to understand, these people are willing. Why would we want to kill them? They keep coming back, and we keep having donors. Less mess, less fuss. Less police activity. But of course, not being from where I am from, you wouldn't know that our presence is widely known in the world. We don't hide. We have rules we must obey. Vampire and human rules."
Rules that he wasn't paying much attention to here, but whatever.
