I want something to drink.
What exactly do you want?
I really want an Iced Skinny Mocha.
From Starbucks?
Yes.
What size did you want?
A Venti.
Oh. It looks like they are out of that size.
Oh man! Is it available in a Grande then?
Yes, it appears that it is.
Cool. I will take that.
Anything else for you?
Make sure they add whipped cream on it.
Let me check if they will let you because it doesn't appear that is an option.
Ok.
So they can't add it to this drink.
Oh man. What is this! Fine. I guess I can do without.
So you want the Iced Skinny Mocha in the size Grande?
That is correct. 
Ok. Your drink is ordered and will be ready for pickup in 15 minutes at the Starbucks on Olentangy River road. The receipt is being sent to you viz text message.
Hooray! Thanks a bunch.
No problem.
