U: I need to get to Cambridge on Sunday. Can you find me a train from Kings Lynn please?

S: We have several different time slots for Sundays train to Kings Lynn. What time is good for you?

U: I need to leave after 15:00.

S: The first train to Cambridge from Kings Lynn departing after 15:00 is the TR2965, leaving at 15:11. Would you like to reserve a seat on this train?

U: Yes.  Please book that for 3 people.

S: I booked the train. Your reference is HFQYOUMG. Do you need anything else?

U: I am also looking for a hotel on the north side of town with a 1 star rating

S: What is your preference on price?

U: I do not have a preference on price, but it must include free parking.

S: I'm sorry, we don't have any hotels fitting your criteria. Would you like to search for something different?

U: If there is no such hotel, how about one that has a star of 4

S: I'm sorry I do not have any 4 star hotels in the north part of town with free parking. Is there anything else I can do for you today?

U: Huh. That's odd. I was told there was a good one.

S: On the north side there are 2 moderate priced hotels both have free parking and internet. They are both 2 stars. Would you be interested in one of these?

U: I really would prefer a 4 star hotel. Can you please look again on the north side?

S: I looked again, and there's nothing meeting your criteria. We have several 4 star guesthouses in the north with parking, would that work?

U: Sure, I'll need it for the same group of people for 3 nights.

S: Would you like me to recommend a 4-star guest house is the north?

U: Would you like me to book it for you ?

S: I would recommend the acorn house.

U: How are the breakfast options there?
S: From what I see in the reviews, the breakfast at the gate corn guest house is very good, and very diverse. Would you like to know anything else?
