All U.S. Starbucks Closing For Three Hours Today

If you need an afternoon pick-me-up, don't get your latte too late!

Starbucks is shutting down all of its stores in the U.S. tonight for three hours. All 7,100 stores will be closed from 5:30pm - 8:30pm local time to re-train the baristas. The retraining is part of the company's plan to stimulate growth, as sales have been lagging for the last few months.
