U: I need to book a nice expensive restaurant in the centre please.

S: There are several nice expensive restaurants in the centre area.  Is there a particular food type that interests you most?

U: I don't have a preference. I need a table booked for six people at 13:45 on Thursday, though.

S: I am sorry none of the listings have tables available for that time, is there another time that will work?

U: How about 12:45 instead?

S: Sure. Kymmoy, a good Asian Oriental restaurant has space. You are reserved and your reference number is L7HRCY1K. Can I help with anything else?

U: I want to make sure that they have great service, do you know?
S: A customer who has been there says that the staff is very friendly and that they even have a sense of humor.
