Conversation - between librarian and student

For asking information politely, we use modals like can and could.

Your school has decided to send you for a competition on Subramaniya Bharathiyar. You go to the library and talk to the Librarian.

Student : Can you tell me if our library has a book on Bharathiyar’s Poems?

Librarian : Yes, we have.

Student : Could I borrow it for a few days?

Librarian : Yes, of course. But someone has borrowed it.

Student : Can I borrow it on Friday?

Librarian : Yes.

Student : Can I xerox. a few pages from the book? Could you permit me?
