Customer: Do you have any medical textbooks?
Bookseller: Sorry, no. They go out of date so quickly we don't stock them, but I can order one in for you.
Customer: I'm not worried about it being in date.
Bookseller: Does your university not request you have a spesific edition?
Customer: Oh, I'm not a medical student, I just want to learn how to do stitches.
Bookseller: ...Right.
Customer: Do you have a book on sewing, instead?
