I am looking for a train that departs on Friday.
Are you looking for a train or a taxi? Where would you like to depart from?
Actually, I'd rather find information about a park, somewhere on the south end of town if possible.
Sure.  There is a cinema at cambridge leisure way.  Would you like to have more information about that?
No thank you.  I was actually looking for a park and not a cinema. Is there a park on the south side of town?
There are two parks in the south area of town. Sheep's Green and Lammas Land Park Fen Causeway and Wandlebury Country Park. Would you like to know more about either?
Yes, could you give me the postcode for Wandlebury Country Park?
The postcode for Wandlebury Country Park is cb223ae.  Do you need any more information?
Yes. I'd also like to book a hotel for 4 people.
There are 4 hotels in the south area. Would you like more information about them?
Is there a hotel called Hobsons House?
Yes, Hobsons House is a guesthouse in the west side of town, moderately priced. Would you like to book a room there?
Yes, I want to book it starting Wednesday for 4 nights. It should be for 4 people.
Sure, I booked it. The reference number is ZZAG4CC0. Can I help you with anything else?
I would also like a taxi and need to leave the hotel by 24:00.
I booked a Grey BMW for you.  Contact number is 07674785163.  Can I be of further assistance?
No, that's all I need.  Thanks.
Great! Have a wonderful day! Goodbye!
