Ever lose your luggage while flying? How about having one of your possessions damaged by the airline? That's what happened to a Canadian guy named Dave Carroll who went on tour with his band and flew United Airlines to get to their gigs.
When they arrived, Carroll's $3,500 guitar was broken. After going through the usual channels, he had no luck getting reimbursed for the broken guitar, so he turned to the internet and posted the youtube video below called, "United Broke My Guitar."
In just two days, so many people viewed the video and contacted United that the company's CEO finally contacted him, replaced the guitar, and asked to use the old one for customer service training at United.
