I need to find a train that leaves on Wednesday and arrives at its destination by 12:30. Can you help?
There is a train leaving from London Kings Cross at 11:00 and arrives by 11:51.
Thank you very much.
You're welcome.  Is there anything else I can assist you with? 
I want to book that train for 6 people.
I can go ahead and book those for you.
Great, can I get the reference number for the train? Also I would like to find a moderate price Cantonese restaurant.
Ok I will book that for you and get you a confirmation number
Great Please provide the reference number and then let me know about the restaurant.
I apologize the trains available arrive in Cambridge at 12:08. Would you like me to book this?
No. I need a train that arrives by 12:30 and departs from Stevenage, not London Kings Cross.
The closest one is TR4626, which arrives in cambridge by 10:43. Want me to book it?
Sure. Once again, it'll be for 6 people. And PLEASE remember the confirmation number this time!
Okay, booked as requested. The reference is 3ZQAT0V1.
Thanks that's all for me today
Have a wonderful time.
