U: I need to book a train from Cambridge to Stevenage.

S: What day would you like to depart?

U: I am leaving on Tuesday, and would like to arrive by 8:30.

S: When would you like to depart Cambridge? I have multiple options that would have an arrival time prior to 8:30

U: Departure time is flexible, but mid-day would be nice.

S: There are 2 midday trains: TR6009 departs at 11:21 and TR0743 departs at 13:21.  Could I book one of these for you?

U: Yes please, the TR6009 sounds good.

S: Ok. I will book the TR6009 for you. How many tickets should I book?

U: Just one please.

S: Booking was successful, the total fee is 12.8 GBP payable at the station and your reference number is 7HK6895I. Can I assist you any further?

U: Yes.  I would like a guesthouse with free wifi, please.

S: Sounds good. I will be glad to take care of that for you.

U: Thanks! I need a 0-star place.

S: I found 2 places matching that, city centre north b and b, and el shaddai. Which would you like to book?

U: Can you tell me if either of these have free parking?

S: Yes, both the city centre north b and b, and el shaddai have free parking. Do you have a preference?

U: Yes, can you check and find the one that is known to be quiet throughout the day?
S: Each establishment, the City Centre North B and B and El Shaddai have mixed reviews in regards to their noise level, as at times it's quiet, and at others, disruptions are present.
