S: Yes. Shall I book it?

U: Yes, could you please book me a table for 5 at 14:30 on Friday?

S: I've made those reservations and your reference number are  OZZGLCVB.

U: Thank you. That's all I need today!

S: Okay I am glad I could be of help. Thank you for calling.

U: Hey, wait,  just a second! I just remembered, I need a place to stay with 4 stars, preferably a hotel.

S: There are 3 places available. Do you have an area in mind?

U: No, I don't have a preference. I'd just like it to be expensive, please?

S: i have 2 places. the huntingdon marriott hotel and the university arms hotel. which would you like?

U: Whichever one has cleaner rooms. Dirty rooms are unacceptable to me.
S: I'm not sure about the university Arms Hotel, but the Huntingdon Marriott hotel has bad reviews for their cleanliness.
