hello
Hello, how can I help?
I'm John. I'd like to book a room at the Hilton Hotel for the dates May 1-19. 
Do you have any other requests?
No, that's it. That's the only hotel and dates I am interested in. 
I'm very sorry, but there is no room available at the Hilton Hotel for your requested dates.
All right. Thank you for trying. Goodbye. 
Is there anything else that I can do for you?
