I've looked everywhere!

What is with these people??

Customer: I've looked EVERYWHERE for this book. Do you have it?
Me: Yes.
Customer: I've seriously looked EVERYWHERE in town for this book. I was at Wa**art and Ze**ers and the grocery store and Everyone kept telling me to check here so you were my last hope.

*In Brain Commentary*
Really? You looked EVERYWHERE and they ALL told you that you should try the BOOKstore for the BOOK you are looking for?

Who are these people and why are they all customers at THIS store?
