Hello I am looking for a guesthouse please.
I have 24 guesthouses in Cambridge.  Do you have an area of the town you'd like to stay in so we can narrow down this list?
I would like to stay in the west. I prefer the hotel to have free wifi and be a 3 star. 
There is the hobsons house which is 3 star and has wifi and free parking.
Could I please get the postcode, and the address for this guesthouse?
Sure the postcode is cb39lh. Their address is 96 barton road.
Great. I'll also need a train going to cambridge.
And where will you be departing from? 
I'm departing from leicester. The train should leave on monday.
I've got 19 trains that leave on Monday.  What time would you like to arrive?
I would like the earliest train available please. Can you tell me the train ID and travel time please?
The TR3173 leaves at 06:54 for a duration of 105 minutes. Would you like a seat booked?
Not right now, but I do need to know the fare for that train.
The fare will be 37.80 pounds. Can I help you with anything else?
Nope, I think that's it for today. Have a nice one. Goodbye. 
You're welcome. Enjoy!
