I am looking for the Addenbrookes Hospital. I am wondering if they have a trauma and orthopaedics department?
Yes, Addenbrookes Hospital has two trauma and orthopaedics departments. Would you like the phone numbers?
No, I just need the postcode, please.
That's no problem. The postcode is CB20QQ. Can I assist you with anything else?
Can you book me a cab to take me to and from the hospital.
At what time? From where are you going?
I'll have to get back to you on that.
Is there anything else you need assistance with?
No, that will be all. Thank you for your help! 
Thank you for using our system!
