I want a train leaving on sunday. 
I can help with that. What is the date and time you would like to leave?
I need to leave cambridge and go to kings lynn and arrive by 16:45 on sunday
The train that will have you arrive closest to the time of 16:45 is TrainID TR9024. Would you like me to secure a reservation?
Yes please.  And can I have the reference number?
How many tickets do you need?
I changed my mind, don't worry about getting me a train reservation. Just please recommend an attraction to visit on the West side of town
I would recommend Churchill College on Storey's Way. They have free admission. Would you like anything else?
Yes. May I please get the phone number to Churchill College?
Yes the number is 01223336233. Is there anything else you need assistance with today? 
No that will be all! Thank you!
I was happy to help you today. Please contact us again, if you need further assistance. Good-bye.
