I'm looking to book a train that will depart out of Cambridge.  Can you give me information about trains that leave Cambridge and arrive in Norwich? 
Of course. There is a train leaving Friday at 5:36. Would you like me to book it for you?
What time does it arrive?
It arrives by 06:55 would that be okay to book for you? 
No I need one that arrives at 16:15.
I'm afraid 06:55 is the earliest I could find. 
What?  16:15 is later that 6:55.  Are you saying you have nothing arriving in almost 10 hours after 6:55?
TR2534 arrives that time. can i book for you?
TR2534 arrives at what time?
Sorry, there was a miscommunication earlier. TR8314 is your best bet. It will arrive in Norwich at 15:55 on Friday. 
Yes I would like this train booked. I need ticket for 4 people. I also need the reference number please.
Okay, your booking was successful. The total fee due at the station is 70.4 GBP. The reference number is 8RU6MZ5J. 
Okay thanks. Can you also help me find somewhere to stay? I'd like a guesthouse in the north preferably with a 3 star rating.
I have 3 star guesthouses in the north. One has free wifi and parking while the other has neither. Which one would you prefer?
The one with wifi will work. I need to book it for Friday, 5 nights, 4 people.
No problem.  I have the rooms booked for you.  What else can I do?
Reference number please, come on, this is taking too long.  And I didn't even get the hotel name from you, is there a manager?
I apologize. You're booked at the Hamilton Lodge and your Reference number is : UC7W5EFU. Can I assist you with anything else?
That was all I needed.
Thank you for contacting us have a nice day.
