I am looking for a college attraction to go to in town.
There are several colleges in either the centre or west part of town. Which area do you prefer?
The centre please.
There are 13 colleges in the center of town. Does entrance fee matter to you?
Not really, but what is the fee?
Most are free, but Corpus Christi has a 2 pound fee, Saint John's has a 2.50 pound fee, and Trinity has a 1 pound fee. 
I need a train that leaves at 20:45 from stevenage to cambridge
What day would you like to travel by train?
I would like to leave on Wednesday.
There are 10 trains, TR9448 leaves at 5:54 would that work for you?
That works can I have the travel time for that please?
TR9448 leaves at 05:54 and arrives at 06:43. The travel time is 49 minutes. 
I've mixed up my locations. I actually need a train that departs from Cambridge and goes to Stevenage.
I only have two trains that leave from Cambridge Wednesday. The TR9016 departs at 21:21 and the TR6387 departs 23:21.
What is the price?
Both options are 12.80 pounds.  Would you like to book one of these options?
Can you tell me the duration of travel time please?
Yes travel is exactly 49 minutes.
What about the train ID?
The train ID for the departure at 21:21 is TR9016 and the trainID that departs at 2312 is TR6387. Would you like me to book on of these for you?
I need an earlier train.
TR9016 is the earliest departure after 20:45. Would you like to change your specified time?
No, TR9016 will do.
