This Saturday, I need to take a train from Ely to Cambridge.  Can you assist me?
sure, do you know what time you want to arrive?
I want to arrive by 11:30.
I have a train that arrives at 9:52. May I book it for you?
Please. I'll need 8 tickets.
Your booking was successful, the total fee is 28.16 GBP payable at the station. Reference number is : X3KOQ6Z3. Anything else I can help with?
Yes, I need a place to dine, preferably in the Centre and I would like it to have modern European food.
There are several options. Is there a certain price range you prefer?
The price doesn't matter whatever you recommend is fine. As long as they have a table for 8 at 15:30 on Saturday. 
How does the Galleria sound, moderate price?
That sounds good! Could you book it for me? 
I waqs unable to book that for you, Are there any other interest you may have ?
Would Thursday work better for the booking? 
I'm not able to book that either?
Hmm could you try again maybe? 8 people at 15:30 on saturday. and if that doesn't work, then thursday.
Sorry, it looks like my system is still down. You may want to contact the restaurant directly.
Can you try again please?
For how many?
There are eight of us.
Sorry the system is down. Please contact the restaurant directly at 01223362054. Anything else?
Thank you very much. Goodbye
