"I'll grab a ____________ Americano, ________________ Black, _______________ Leave space for the cream"

Is this an American ordering an Americano - by its name - with milk? If you want milk, why ask for it black? Why not say milk?

Made it with milk, customer went away happy, even complimented the drink... sometimes as a barista you need to over-communicate to clarify important details, other times you trust your gut instinct and avoid adding friction to the experience. This time it paid off.
