U: I need a train departing Cambridge and arriving by 08:00.

S: What is your destination and your departure day and time?

U: I would like to travel on Monday and arrive in Kings Lynn. It does not matter what time I depart.

S: Alright, you have three options: leaving at 5:11, 6:11, or 7:11. Would you like to book one of these trips?

U: Yes. I would like to book the 5:11. I also need the train ID and travel time.

S: No problem. It's 47 minutes long and the train ID is TR7964.

U: I'd also like to find a place to stay. Four stars, please, and on the west side of town.

S: Let me see. I have three options available, two are cheap and one is expensive. They all include free internet and parking.

U: Are any of them guesthouses?

S: finches bed and breakfast is a 4 star guesthouse with free internet and parking.  Would you like to book it?

U: Are the bathrooms clean at that guesthouse?
S: A reviewer said that the bathrooms were clean, but the rest of the room was not. Is there anything else I can help you with?
