U: Can you help me find a train departing from birmingham new street going to cambridge?

S: Absolutely. What day do you need to get to Cambridge, and at what time?

U: train should arrive by 21:00 and should leave on tuesday

S: There are trains that meet those requirements leaving once an hour starting at 05:40.

U: Can you assist me with booking one?

S: Lets narrow down the time a little, the TR 3802 leaves at 17.40 and arrives at 20.23 so that gives you a little extra time, would you like me to book you?

U: That would be great. I also would like to book a guesthouse for my stay.

S: Okay, great. You have a lot of options. Would you like to narrow it down by area, price range, or stars?

U: Yes. It should have 2 stars and include free wifi.

S: I do not have any in that star range. Shall I try something else?

U: Maybe a star rating of 3 would be good.  Is there anything available?

S: yes when were you planning your stay and for how many people?

U: I need the reservation to be for 2 people and 2 nights please.

S: Okay! Starting when?

U: On Tuesday please.

S: I've booked your room for two at Hamilton Lodge. You'll be staying for 2 nights beginning Tuesday. Your reference number is 3NT2B4SP. Can I help you find anything else today?

U: Does the hotel have comfortable mattresses?
S: The Hamilton Lodge has two reviews about the mattresses being comfortable, and one saying the mattress needed replaced.
