U: I need a train leaving Cambridge after 21:15.

S: Ok, I have 5 options for you. The earliest leaves at 21:59.

U: I would like to travel on Saturday and go to Leicester.

S: The TR7610 leaves Cambridge at 21:21 and arrives in Leicester at 23:06. Would you like to book a ticket?

U: Yes, can you book me a ticket for 3 people?

S: Booking was successful, the total fee is 90.72 GBP payable at the station. Your reference number is DKV6X3Z3

U: Wonderful.  Can you tell me if A and B Guesthouse is still around?

S: Yes I have a listing for the a and b guest house.

U: Does a and b keep a high standard in room cleaning?
S: The hotel is not known to have clean rooms so that may be a problem for you. Is there anything else I can help you with?
