U: Yes, would you be able to help me find a train leaving from Cambridge?

S: I can definitely help with that. What day would you like to travel? And what is your desired destination?

U: I want to travel on Saturday from Cambridge to Kings Lynn.

S: There are 19 different trains on Saturday from Cambridge to Kings Lynn. What time would you like to arrive by?

U: I would like to leave after 14:30. Could you find me a train for that time?

S: The first train to leave after 14:30 is TR6982 and leaves at 15:11

U: OK, could you book me 7 tickets for the TR6982?

S: Booking was successful, the total fee is 54.88 GBP payable at the station. Is there anything else I can help you with?

U: I'm looking to stay in a guesthouse while I'm there. I'd like a place that has free parking.

S: There are a number of guesthouses.  Do you have a price range and an area that you prefer?

U: No. What is available?

S: I have 21 places that fit what you want.  Do you have a price preference?

U: Not at the moment.  Can you recommend any moderately priced guesthouses to accommodate  7 people?

S: Is there a specific area of town you would like to stay in?

U: Not particularly. I just need one for 5 nights starting Monday. Whichever you recommend.

S: I am very sorry, but I was unable to book a guesthouse, would you be able to check in at a later day, or could you stay for a shorter period?

U: Can you book it for 3 nights?

S: You're booked at the Acorn Guesthouse for 3 nights, 7 people, starting on Monday. Your reference number is WU51A5WI. Can I help with anything else today?

U: Could you kindly confirm that the Acorn Guesthouse has showers with high water pressure?
S: Unfortunately reviewers thought that the water pressure was too low at The acorn guesthouse. Is there any other information that you need?
