What's the point in having a machine for special coffees?
Usually coffee shop staff do not know what kind of coffee they are selling from the device.
What IS know in this equation, is the higher quality expectation when customer orders special coffee. -And for this expectation regular coffee shop answers by ignorance - selling a product they have no control over (not even quality control)?!
Why do they even bother, when they would have perfectly ok coffee on the pot to serve - with normal expectation level? -Maybe the disappointment would be lower..
