This is the current world's most expensive Starbucks drink, the $54.75 Sexagintuple Vanilla Bean Mocha Frappuccino, a 128oz (that's a gallon) behemoth with 60 shots of espresso. Twitter user Andrew Chafari got it for free by using his Starbucks gold card. Of course it took making friends with the baristas at Starbucks to make it happen. Some other lady actually managed to order a drink that cost $56.70, but that one is disputed as the most expensive because she didn't bring a cup large enough to fit the whole drink. DISQUALIFIED. Granted pretty much anybody could order the most expensive Starbucks drink if they wanted provided 1) they have a friend who works there and 2) brought in a cup the size of a kiddy pool. I'm going to go this afternoon and order a $600 drink. Then take a picture of the drink and receipt and run. Sure my friend might get fired, but his house parties always suck anyways.
Thanks to lib, RosettaStoned and Allyson, who agree if the person in front of you at Starbucks starts ordering the most expensive drink, your only option is to tap them on the shoulder and challenge them to a duel to to the death.
