A real live Death Eater! My goodness, they are everywhere.
Other than the obvious negative attributes one has to assume of all Death Eaters (being evil, serving the Dark Lord, disliking the super awesome Neville Longbottom, being mean to Harry Potter, etc.) this particular Death Eater seemed quite nice. She sold me my Coke Zero and my sunflower seeds quickly and efficiently, and if any evildoings happened while I was in the 7-11, I was unaware.
