Starbucks is testing a program where you can, "Borrow a cup." You get a cup, pay a dollar deposit, and then when you return it that dollar is given back. So...kind of like mugs or tumblers? Five Seattle stores are testing this out and it sounds like it is going well. The cups are returned, sterilized, clean, and then sent back out with the coffee order of the next person to use them. So yeah, like using mugs or tumblers, how revolutionary! I'm being silly, but anything good for the environment is obviously a smart thing to try out. I applaud Starbucks for trying to cut down on waste.
