Please help me book a train from Cambridge to Stanstead Airport.
When are you planning to travel?
Monday. I need to leave after 18:15
The earliest train after that time is TR7696 that leaves at 18:40 and arrives at the airport by 19:08. Would that work? Or, I have later trains. 
Yes, the 18:40 would work, how much does it cost?
The price per ticket is 10.10 pounds. Would you like me to go ahead and book it for you? If so, for how many tickets?
That's OK, no thank you. Are there any nightclubs in town?
Yes there's 6 in the centre and 1 in the south. 
What's the postcode for the one in the south?
The nightclub called the Place is located at the postcode cb23hg.
Yes, thank you.
Is there anything else I can do for you?
No thank you that is all.
enjoy your stay in cambridge!
