You and your 4 best friends have just graduated from university and celebrate by going out for drinks. You head to the local cocktail bar, famous for the following 9 cocktails: Aviation, Bronx, Caipirinha, Grasshopper, Hurricane, Kamikaze, Manhattan, Negroni, and Vesper.
In the spirit of your celebration, the bartender tells you that if you can identify all 9 cocktails after the third round of drinks (one drink each per round), he won’t charge you for the cocktails. The group then proceeds to order 5 drinks per round for 3 rounds. Although none of you know anything about cocktails, with clever ordering and deductive reasoning you find a way to do it. How?
This is not a trick question. The bartender doesn’t tell you which drink is which when he brings them and there are no pictures of the drinks, etc.
