Good morning assistant, I need to order some coffee from Starbucks.
ASSISTANT
Of course. Which location would you like to order from?
USER
I think the place on Green Street, it's not a far walk for me to go pick up.

Got it. Are you looking at their menu online now?
USER
Yes, just deciding what to order...
ASSISTANT
Ok.
USER
I think... A caramel cloud macchiato, tall, would be perfect.
