I took my first drink, can I have another?
Believe it or not, Starbucks will go out of its way to make sure that every customer is thoroughly satisfied. In addition, Starbucks baristas don’t particularly care about how much money the company loses since they make a fixed salary and wage. If you want to score a free Starbucks coffee, just do the following.

Go to a busy Starbucks outlet, order a drink, have a friend pick it up, then go up to the counter and claim that someone took your drink. There’s a pretty good chance that nobody’s keeping track of who’s ordering what, so they’ll believe your story. Alternatively, you can say that something’s wrong with your drink, and they’ll make you another one, free of charge.
