I need a train to Norwich. I need to get there right before 20:45.
And what day are you traveling?
I will be leaving on Sunday.
The train that arrives closest to 20:45 is TR9083 arriving at 19:55. Shall I book it?
Yes, I will need tickets for 5 people please and a reference number.
I was able to book that for you. The total fee is 70.4 GBP and the reference number is LIW5CYJ0. Is there anything else I can help you with?
I'd like to find somewhere nice to stay, too. Can you help me find a hotel?
Yes, I can definitely help you with a hotel.  Do you have a price range, hotel type, or area that you are wanting to stay?
I would like an expensive guesthouse that includes free wifi and has at least 4 stars.
I'm sorry I have no expensive guest houses listed. Could I perhaps interest you in a more moderately priced guesthouse?
How about simply a cheap one?
There are 7 options available. Is there a specific area that you prefer?
No, I just need a place I can stay for 3 nights for our group starting on Saturday.
I'm sorry, all hotels are asking you to book another day, or a shorter stay. 
Can you check again? A cheap, 4-star guesthouse for 3 nights, starting Saturday, for 5 people?
I did find a hotel for you. We've booked you at the Alexander Bed & Breakfast for 3 nights. Your reference number is 244GZSGM. Is there anything else I can help you with?
That will be all, thank you very much!
You're welcome. Have a nice day.
