I refer you to Chapter XII
"Things I Said to The Matlock Casting Director" (its not pretty)
"Lunches with Agents"
(very funny section where one agent says "I'm not here to save you!" and another says
"I'm paying, but don't go crazy." and finally, an agent whose 'shop' the author had been with for over five months says, after ordering, "So, when were you thinking
of joining us?")
