Hello, Assistant. I want to buy movie tickets for Pet Semetary.
What is the location of the movie theater that you want to go to? 
Bellingham, Massachusetts
Do you want to go see a movie at Regal Bellingham Stadium?
Yes.
How many tickets would you like to purchase? 
Two adult tickets.
What date would you like to purchase tickets for? 
Today at night.
There is only one showtime available at 10pm. Would you like to purchase two adult tickets for this showtime?
Is it in 3D?
No. There are no 3D showings for today at this location. Would you like to continue with the purchase.
No. I want to see the movie, Dumbo, instead.
Please confirm the date, location, ticket information, and type of theater you would like for the Dumbo movie.
Two adult tickets for Dumbo at Regal Bellingham Stadium for the regular theater for a showing after 10pm.
The last available showing for your requested preferances is at 9:30pm today. There are no showings after 10pm. Should I purchase two tickets for 9:30 instead?
No, nevermind then. Cancel my entire request.
Your purchase request has been cancelled. Is there anything else that I can assist you with?
No. Turn yourself off.
Ok. Goodbye.
