Hello can you help me book a flight please?
Where are you departing from?
I'm going from Los Angeles to Pittsburgh.
On what day do you want the plane to arrive?
On the 8th please.
Unfortunately there are no flights that match your search. Would you like to change any of your criteria?
Any date around there will work.  
Right, I found an Economy flight with Delta for 316 credits
 that takes 4 hours to get to Pittsburgh.
Not bad.  I don't need to book it just wanted to get a feel for prices.  Can you help me schedule a meeting?
With whom would you like to schedule the meeting?
Fred.  He's been dodging me for months now.
Start and end tome
3 pm start 4 pm end. 
Can I get your name, please?
Yes Sarah Brown.
Fantastic, your meeting with Fred has been successfully scheduled for Sunday, -.
Oh great!  His dodging days are done.  Ok onto dinner tonight I would like a reservation at The Porch for 5pm.  Just 2 of us.
I am sorry, but the reservation request was not successful.
Ok try Lucca then I hear it's nice as well.
I am sorry, but the reservation request was not successful.

Can you change the time and get something to work for me?
Excellent, your reservation at the Cactus Club is confirmed!
Ok great!  Do you think you could help me RSVP to a party also?
At what venue is the party taking place?
The Porch!
Do you require parking at the venue?
Nah we will all arrive in the limo probably.
When are you planning to arrive at the party?
6 pm would be the best time.  But we are flexible.
