I want to pick up a pizza on the way home, I'm too tired to cook. Can you order Channello's for me?
Sure, what do you want. 
A small pizza. Extra cheese and pepperoni.
You got it.
Do they have an option for white sauce instead of marinara?
Yes they do.
Let's get white sauce tonight.
Huh. It looks like white sauce is only available on large pizzas.
I'll take a large then. It'll feed me for a couple of days.
Ok. Large pizza with white sauce, extra cheese, and pepperoni.
Right.
Let me log into your account... ok, ordering now. 
Thanks.
It looks like this will be available for pickup in about 25 minutes.
That works for me. 
Ok, I put the order in. They will text you the receipt, as usual. 
Great. 
Can I help you with anything else? 
No, that's it for the night. You are officially off duty. 
Thanks. Enjoy that pizza!
