I need a train that gets me into Cambridge by 21:30
sure, what day are you traveling?
I'm leaving on Saturday. I am coming from London Kings Cross. 
The TR7223 arrives in Cambridge at 20:08. Will that suit you?
Yes, could you book me tickets for 7 people on that train?
Absolutely! Go ahead and pay 132.16 GBP at the station for the 7 tickets. Would you like your reference number?
Can you recommend a cinema in the east?
There are no cinemas in the east. Can I help find something else?
Actually, yes, I do need that reference number on that train.  And, maybe you could find a museum instead of a cinema?
reference number is K13L3ILC. 
What about a museum? Are there any of those in the east? If so, please give me some additional information including the entrance fee.
There are 4, I would recommend Cambridge Artworks 5 Greens Road, postcode cb13ef, number 01223902168. There is no entrance fee. Is there anything else I can assist you with?
Thank you.  You have covered everything.
