U: I'm looking for a 4 star hotel.  Can't wait to check out Cambridge.

S: Yes I have both guesthouses and hotels that are 4 stars. Any preference on amenities or price?

U: I need  it to have free parking too.

S: I can suggest allenbell.

U: is it expensive?

S: no quite cheap actually

U: Hmm, I don't usually like the cheaper places. How about anything that is moderately priced?

S: There is nothing that matches your criteria.

U: No problem. I would like a place to eat. Chinese food around the centre of town.

S: Okay I have many choices. Do you have a preference for price?

U: yes is should be expensive

S: I've heard great things about HK fusion.

U: Actually, I am looking for one that is in the same price range as the hotel for 3 people at 14:45 on Monday.

S: I have 3 options for moderately priced Chinese in the centre. I would suggest jinling noodle bar.

U: That will be nice. Can you book it for monday at 14:45 for 3 people?

S: Ok, your booking was successful. The table will be reserved for 15 minutes, the reference number is : SBDEVYH9.

U: Thank you. Going back, I don't think we chose a hotel. I need a moderate price guesthouse with 4 stars. Remember?

S: We have 9 moderately priced guesthouses with parking, which side of town are you looking for?

U: I am looking for the centre area.

S: Based on the criteria, I cannot find a hotel. Would you like to try a different preference?

U: What about an expensive one?

S: The jinling noodle bar had already been booked for you, is that not ok?

U: No that is fine but I do need a taxi to arrive at the reastaurant by 14:45 and pick me up from the hotel.

S: I don't see where you have chosen a hotel. Perhaps we should look at that first?

U: Yes an expensive one would be great with a 4 star rating and free parking.

S: The university arms hotel sounds like exactly what you're looking for. Would you like me to book it for you?

U: Are their bathrooms known for being spotless?
S: The university arms hotel customers have stated that the bathroom was clean, cleaned recently, and pristine.
