Customer: So you have all the books right?
Customer: You have all the books that are out.
Me: Ummmm, we have a lot of them.
Customer: I'm looking for a book.
Me: Okay. We are a bookstore.
Customer: I'm looking for a particular book.
Me: That's often the case. What book are you looking for?
The customer tells me and I look it up and end up reserving a copy for him.
Nice enough; sometimes you can't help but laugh though.
