User: Hey, I need some movie tickets for tonight.
Assistant: Okay, I can help you with that. First, what movie do you want to see?
User: I'd like to see Dolittle.
Assistant: Great! Now, what theater do you want to see Dolittle at?
User: Umm, I think the Regal will be good.
Assistant: Okay, now what time do you want to see Dolittle at the Regal.
User: I guess the 8:00PM show will be all right.
Assistant: Okay, what type of screen do you want to see Dolittle at the Regal on?
User: Oh, um, the IMAX one. Hang on a sec. I've changed my mind. Make the theater the Waco Hippodrome.
Assistant: Okay, let me confirm everything so far. You want to see Dolittle on the IMAX screen at 8:00PM at the Waco Hippodrome. Is that right?
