A John T. is a particularly nasty manager at a bookstore. Known for his moodiness, blistering criticism, withering stares and constant whining, he is feared by both empolyees and customers. You might find him lurking in the shadows of the non-fiction section, ready to pounce at your shelving mistakes. He also has a street rep for being one of the best dancers aound, but don't ask him to dance unless you fancy a write-up and or trimination.
