Hello how may I help you? I need some help with theater scheduling. That's what I'm here for. Is "The Waltz Invention" playing tonight? Not tonight, but it is playing at noon tomorrow. Ah, I see. How much are tickets? Tickets are $20 each. And how long does the play last? The play lasts on average 90 minutes. Great. Thanks for all the information. That's all I need to know. You are welcome.
