U: I am looking for a guesthouse in cambridge with free wifi.

S: What price range are you looking for?

U: Expensive and in the north please.

S: My system is not pulling up any guesthouses in the north with free wifi and expensive in price. Would you like to adjust your criteria?

U: Can you check to see if there is a similar hotel in the moderate price range please?

S: I have several moderately priced guesthouses.  Do you have a star preference?

U: Not particularly, but the nicer the better, of course. I'm coming in saturday and staying 5 nights. Can you book it for me? There's 4 in my party.

S: The booking was successful. Would you like the reference number?

U: Yes, I would like the reference number please.

S: The reference number is GF89WKAB, can I assist with anything else?

U: I also need a place to eat that serves british food and should be in the same price range as the hotel.

S: which side of town do you prefer?

U: Doesn't matter to me, what do you recommend?

S: I recommend travellers rest on the west side of town, would you like me to make reservations for you?

U: Sure. Can you book a reservation for the same group of people on the same day at 17:15? And give me the reference number please.

S: Your reservation is booked, and the reference number is I2WJ41ZB. Is there anything else I can do for you?

U: I'm going to need a taxi as well.

S: I need to know which two locations you are going between and your time of travel please.

U: I need the taxi to get us from the hotel to the restaurant before the booked time please.

S: I need the time of travel, name of departure, name of arrival destination please.

U: Well it's going to be from our hotel to Travelers Rest restaurant by 5:15.

S: How many people will be in the taxi?

U: Do they have a nice outdoor dining area?
S: All I know is that there is outdoor dining. There are no reviews about how nice it is.  Would you like me to make a reservation for you?
