U: Hi, can you help me figure out a train schedule, please? I need to travel to London Liverpool Street sometime after 18:45.

S: Where are you leaving from?

U: I am leaving from Cambridge on Saturday

S: The TR2166 train leaves at 19:59 on Saturday, would that work?

U: Yes, may I please have the price?

S: The cost per ticket is 13.28 pounds. Can I assist you in booking a ticket?

U: Yes please.  Also I am looking for a 4 star hotel with a moderate price range.  Can you make a recommendation?

S: We only have guesthouses that fit your requests, would you like a different hotel?

U: A guesthouse in the north should be perfect.

S: How about the Acorn Guest House in the north? It's 4 stars and a moderate price. I would be happy to help you with a reservation.

U: Are there comfortable beds in that facility?
S: The majority of the guests were not happy with their beds with some saying the beds were of poor quality, their backs hurt in the morning, and just all around uncomfortable. One guest did say they had a very comfy bed. Would you like to look at some other places with better reviews?
