Hello how may I help you? I want to know if the Engineering Ethics book is in your library? Let me check for you. Okay. Take your time I don't see that particular book in our catalog. Then how about Books for Dummies in calculus? I'm sorry, but I don't see that title either. Then what books are available in your library? We have a large catalog of books, I'm sorry that the titles you requested were not available. Would you like to try another title? No thanks. Ok, please come back anytime.
