It's started already

Customer: Do you have the new Dan Brown book?
Me: The DaVinci Code is the newest one that's out. Where you looking for Angels and Demons? That's the one the new movie is based on.
Customer: No. I want the new one. The Lost Secret.
Me: They've only just released the news of the the release date of the new book. The Lost Symbol will be out Sept 15.
Customer: No (RUDE) The new one is out. It's called The Lost Secret and that's the one I want.
Me: I'm sorry sir. We have no Dan Brown book called The Lost Secret and The Lost Symbol will be out Sept 15.
Customer: You people don't know what you're talking about. I'm going to go find it at W*****t.


And good luck with that. Last I checked they weren't exactly book experts at W*****t. I feel at least a little sorry for whatever poor schmuck he talks to there. I'm sure he'll be just as fun when he's asking for the non-existing book at a discount.
