Please don't ever tell someone you know how to make a specific drink when you actually don't. I just paid you people 4.50 for a cup of hot milk because the person working didn't know how to make my drink. HOW DIFFICULT IS IT TO MAKE A RISTRETTO SHOT?

We are sorry for the off coffee drink you ordered. Did you order the flat white or the ristretto? Either way you shouldn't have to pay for a drink that isn't made properly. The employee who made your drink is new and was unfamiliar with these rarely ordered drinks. Please come back in for another or a refund, we want you to be happy! Don

A flat white is basically a latte with a ristretto shot. A ristretto is a shot of espresso that uses less water than normal, at higher pressure and higher temperature therefore giving you a more concentrated and less acidic extraction.
