Diane & Mia's Cafe

Here is a story of you, or one of your friends:

 

You go inside a cafe for a meeting and try to buy a drink. Then you find so many unfamiliar Italian words on the menu - too many to ask the barista. After a lot of assuming, you finally decide to order the first thing on the menu, espresso, which is also usually the least expensive one.

How bad could it be?

 

The barista calls your name and hands you a tiny glass filled with dark liquid. You feel something is wrong but decide to give it a try. After the first sip, you immediately regret spending a couple of dollars for this drink!
