I'm thinking about ordering a pizza for lunch. 
How can I help you?
I want you to order a pizza from Uncle Gio's.
What kind of pizza?
One Vegetarian pizza.
Sure, I'll place an order.
Wait, can you tell them I want no onions and to put mushrooms instead?
Sure, what size pizza?
A large.
Anything else with that?
No, just that. 
I just called Uncle Gio's, they are closed for the day.
Okay, can you call Sal's and just get a pizza with mushrooms, garlic, and extra cheese?
Same size?
Yes, a large.
Okay, I placed an order, one large pizza with mushrooms, garlic, and extra cheese.
Great, thank you!
It'll be ready for pickup in 25 minutes. 
And my receipt?
It'll be sent to your phone via text message.
