U: I am looking for a train leaving Cambridge.

S: We have quite a few, I'm sure we'll be able to get you where you want to go. Where is that, exactly?

U: I would like to go to leicester and leave on friday.

S: I have quite a few trains that fit your criteria. Is there a certain time you need to leave or arrive by?

U: May I buy additional wifi data on the train?

S: I'm sorry, but that is not an option on the train. When were you thinking of leaving?

U: Departing from cambridge and I want to arrive somewhere around 20:00, can you get me 7 tickets and I'll need the reference number too.

S: The TR2508 arriving at 19:06 sound okay to you?

U: That sounds great, thank you. Could you book that for me for 7 people? I will need the reference number as well.

S: I completed your booking. The reference number is C11MOBV7. Is there anything else I could help you with?

U: Yes , I also need to find a place to stay. Preferably 4 stars and a guesthouse.

S: Sure! Our database contains 18 guesthouses rated 4 stars. To narrow down the search, could you tell me in what part of town you'd like to stay?

U: I definitely want to stay in the east part of town.

S: I have six entries matching your request.  Would you prefer cheap or moderate price range?

U: The price range doesn't matter, but could you pick one and book it for 3 nights for 7 people starting Tuesday?

S: I'm sorry.  There are no rooms available for that stay.  Can you choose a different day or shorter stay?

U: How about 1 night?

S: I was able to book the A and B Guest House for 1 night.  Booking was successful.
Reference number is : 995PR933.

U: Before I commit to a booking does the hotel charge an extra fee for WiFi?
S: No, WiFi is free for all guests and has good reviews stating the connection is fast and reliable. Would you like to know anything else?
