Hello, I am looking for a train departing from Cambridge, and leaving on Friday. Do you see anything for that time?
There are tons of them! Can you tell me a bit more about your trip so we can narrow it down a little? Where would you like to go?
Yes I want to leave after 13:30 and arrive at London Liverpool Street.
There are 6 options available. Would leaving at 13:59 and arriving at 15:27 work for you?
Yes, that would be perfect.  Can you just give me the train ID for that?
That is train TR4187.  Is there anything else I can help with?
Yes are there any multiple sports places to go in the centre?
There are no sports in the center. Shall I change type or location for you?
Hmm, that kind of stinks. Well, how about a theatre instead? 
I have 4 theaters in the centre area. The mumford is one of my favorites. Can I give you more information on one?
What's the entrance fee?
I am unaware of what their entrance fee is at this time. Sometimes that happens because prices fluctuate and I apologize.  Can I help with anything else?
No thank you, goodbye.
You're welcome, have a nice day.
