This story comes straight from the mouth of my manager.
So, a customer comes in and asks if we have “I Am Malala”. He takes the woman down to the section and says that there is the teen edition and the normal one.
She responds, “Oh great. So I can borrow these then?”
“Um, no. This isn’t a library.”
“So I have to buy them?”
“Oh, maybe I’ll think about it then. I didn’t know I had to buy it.”
