True Blood
Sookie is a waitress for Merlotte's, a bar owned by her boss, Sam Merlotte (Sam Trammel). A rather lousy couple enters the bar, in Sookie's section. She serves them, and when a vampire enters the bar, the heads turn. She accidentely reads the rather rude couple's mind, and hears them both think that when they leave the bar, they will drain the vampire of his blood, a rather expensive substance used and seen as a drug in the series. Sookie leaves in a haste to stop them, and actually does save him. Something rather strange happens (Sookie gains the man's attention by throwing a chain around his neck, and it seems to squeeze itself around him and stay there), it is shrugged off. The woman, speaking for both of them, vows revenge on Sookie for getting in the way and runs off, with her male counterpart trailing behind her.
