IStar -- You have been mislead. Starbucks in Argentina is not Official Starbucks. Nor are any of the Starbucks in South America. Go to the Starbucks official website and look up locations in Buenos Aires, Santiago de Chile, Cordoba, wherever you want in South America and you will see, NONE come up. Then if you google around for awhile you will find the Starbucks Argentina site that clearly states it is Ex-Official. In otherwords, nothing is coming from Corporate Head Office here apart from the rights to sell the coffee in the cups and have all of the pretty looking stuff that goes with it. Some other company has bought the rights to open Starbucks here and in chile. They get to look all pretty and I'm sure they're supposed to work with Starbucks standards but they don' necessarily.
Now I'm sure this is the way it is in most of the world outside of US/Canada, that Starbucks is actually owned by some other entity. However, in Argentina there are huge diferences in customer service and they aren't going to suddenly change that. They will sell the product but they arent going to manipulate their staff members into becoming nice North American barristas.
The Starbucks kids at the SCL airport are much nicer.
Anyway, at the end of the day, Starbucks sucks ass. As a Vancouverite I shun Starbucks and would love to open an Artigiano franchise here instead, however Artigiano is for true coffee lovers and the barristas are craftsmen... I don't know how it would ever go over here! Trying to source quality products and then train an Argentine staff to make artwork in their foam could be a phenomenal task. If Starbucks is 10 pesos for a tall here, Artigiano would end up being about 20!
