How does Paige get a job at the diner, Mercy?

Paige finds herself in a diner called Mercy a few days after she gets off a bus in Cambridge, Massachusetts. Paige is in desperate need of a job, but the owner of the diner does not need a waitress and sends her on her way. Before Paige leaves, she draws a portrait of the man on the back of a menu. The portrait has a picture of a woman with horrible scars on her back. Paige has always had the gift of drawing people's secrets within her portraits, and hopes this time it will get her a job.
