I was reading on a website dedicated to Starbucks baristas about customers who try to cheat the system. They order drinks in a way that makes it cheaper, such as a hot chocolate with a shot of espresso (really a mocha) or an espresso in a venti cup with extra, extra foam (really a venti extra dry cappaccino). Most of the people on this website are in America. I posted that we have never had this kind of problem. The VERY day after I posted this, on two separate occassions, Americans came in and did this. One ordered an espresso in a grande cup and asked for extra foam, another asked for a tall drink in a grande cup and added extra milk from the bar.
I definately agree that Starbucks is expensive, but if you insist on these drinks every day, you have to pay the price. And do they really think they are pulling the wool over our eyes?
