Hi, I'm heading to birmingham new street so please find me a train that leaves on Friday
Are you leaving from cambridge? Is there a time you'd like to leave?
Yes, I'm leaving from Cambridge. Departure time doesn't matter, but I need to arrive by 18:15.
There are 12 trains available for you and the first one leaves at 05:01. Can I book a seat for you or do you prefer a later departure time?
No, I said arrive by 18:15. Try again. 
The closest arrival to 18:15 is 17:44. Would that work for you?
What is the price for a ticket?
The cost per ticket for that train is 75.10 pounds did you still want me to book it for you? 
No, thats ok. I also need to find a cheap Italian restaurant. 
There are 15 Italian restaurants to choose from. Would you like one in a particular part of town?
Any that you choose will be fine. I'll need to book a table for Friday at 10:00. There will be 3 people dining. 
I have you booked at Ask, for Friday at 10:00 for 3 people.  It's at 12 Bridge Street City Centre.  Your reference number is:  IL7HZYW5.
Wonderful! I think that's it, thank you. Goodbye!
You're welcome. Have a great night!
