Naming; the perils of

So when someone pays me a dollar to use the internet here at the liberry I have to make up a name to make the computer happy. One of my coworkers asks the patron for his or her name, another uses his name and a number after it (1, 2, 3, etc.), some use just GUEST. I prefer to name my patrons according to a distinguishing characteristic. Today I've had gray hat, brown hat, XXL (his shirt, not his waistsize!), orangy-striped shirt, etc. I just logged someone in as Brownshirt. Watch out, Asheville, the Nazis are in town!
