Giving tourists a bad name

Customer: Do you have learn Spanish sets?
Me: Sure, over here.
Customer: Oh, these have cds?
Me: Yes, most of the sets come with a cd and the books. That way you can hear and see the lesson.
Customer: Oh, I don't need to hear it to learn it. I'll just know.
Me: Okay. I guess you don't need a set then. These are all the Spanish / English dictionaries here.


Okay then.
