U: I'm looking for an expensive indian restaurant.

S: I have many. Is there a certain area you are looking for?

U: Yes it can be in centre. I would like to book it for 1 person at 20:00 on Saturday.

S: OK, I booked a table for you at Saffron Brasserie. Your reference number is 65G14AF2. Can I help with anything else?

U: No thanks, that will everything.

S: Thank you for using our service today.

U: You're welcome, thanks.

S: Are you sure there is nothing else I can do for you today?

U: I'd like to find a guesthouse in the north.  I want it to have 2 stars.

S: There are no guesthouses that meet your criteria, can I check something else for you?

U: Are there any hotels in that area instead of guesthouses?

S: There is the ashley hotel or the lovell lodge. Would you like me to make a reservation?

U: I am wondering if the shower has a powerful showerhead.
S: One reviewer said that the water pressure in the shower was too low. Is there anything else you need?
