At the bookstore

So I'm at a bookstore on Thanksgiving night and there is a lady looking for The Scorch Trials.  But she can't find her list and the store is closing soon so the employees are doing other things.  I hear her say "The Scorch Trials" to her husband and as I'm just standing there waiting for my husband and sister to finish up, I say "James Dashner. That's the author."  Then her husband just smiles at me and they continue to wait on the saleclerk who when he finally gets to them, saying "James Dashner."  I really wanted to say "HA! I'm a librarian.  A professional at this."  But I didn't.
