User: I am looking for a drama or suspense type movie showing at the theaters in Houston, Texas.
Assistant: Ok, I will be glad to help you with that. Let me take a look.
User: Also, I would like to watch a digital showing, please.
Assistant: Ok, not a problem. I am showing two movies that you might like. Knives Out and Bombshell.
User: Bombshell sounds great. I need the showing time to be 7pm
Assistant: I am sorry about that but Bombshell is only playing at 5:20pm
User: Ok, that will not work. What showtimes are available for Knives Out?
Assistant: Knives out has three different showtimes to choose from. 4:30pm, 7:30pm, or 10:30pm
User: I would prefer something that starts at 7pm.
Assistant: I am sorry. There is not a showtime for Knives Out available at that time.
