If you find you need proof of credentials I believe there is someone in town that can help you. Though I'm afraid I don't know who has taken over the forging of identities these days. The Winchesters might be the ones to ask.
The Roadhouse is a local business but I've known displaced to have worked there for a time. Miss Branson also runs a bar, Bed of Roses. I myself co-own, manage and fill the roll of head baker, at a bakery near the edge of town. Most of my staff is local though I have recently hired Scorpius Malfoy to work up front. There is also the Youth Center. These are only the ones I can recall at the moment. Perhaps someone else will mention those I might have missed.
