user: I'd like a Mocha. It'll be for Marie.

assistant: Would you be so kind as to confirm that your order has been received accurately?

user: Actually, no, I'd like to change it. I want a decaf Mocha instead.

assistant: Sure. Can you confirm that we have your revised order correct before we begin making it?

user: Yes, that's what I want.

assistant: Great. Your order will be up at the coffee bar soon.
