CHICAGO (WLS) -- Starbucks stores in Chicago and around the country ended up giving away coffee and other drinks to many customers Friday night.
The coffee shop chain decided to do that after a computer glitch made it impossible to ring up sales or take credit cards.
Some stores closed, while others that stayed open saw a lot of traffic and word spread on social media about free coffee.
