How does Clay feel about his job at the bookstore in the novel, Mr. Penumbra's 24-Hour Bookstore?

From the text:

“As a professional capability, this might not be as marketable as web design, but it’s probably more fun, and at this point, I’ll take anything I can get. I only wish I has to use my new skill often. Mr. Penumbra's 24-Hour Bookstore does not operate around the clock due to an overwhelming number of customers. In fact, there are hardly any, sometimes I feel more like a night watchman than a clerk."
