Hey can you order a pizza for me?
Yes I can.
I want to order the pizza from Papa John's.
Okay what type of pizza would you like?
I want to order a buffalo chicken pizza.
What size would you like?
I want the medium size pizza for $10.99.
It appears that they don't have that pizza available. Would you like to order another topping instead?
Yes. I'll take a chicken bacon ranch pizza instead.
Did you still want a medium size pizza?
Yes. 
Okay perfect did you want anything else? 
No that was it. 
OK I will send that order in now to Papa John's.
