(A customer approaches me holding an audio book.)

Customer: “What’s this?”

Me: “It’s an audio book.”

Customer: “What’s that?”

Me: “Well, it’s books read aloud so people can listen to them instead of reading the text.”

(The customer looks horrified.)

Customer: “Do you have more?”

Me: “Oh yes, those shelves behind you there.” *pointing*

Customer: *looking at the rows of audio books* “That’s disgusting! People who can’t read shouldn’t be allowed in libraries anyway! You shouldn’t pander to them!”

Me: “Well, it’s also for people who have low or no vision.”

Customer: “They have no right to books, either!” *storms out*
