Last week, Joey Prusak was an unknown 19-year-old Dairy Queen manager in Hopkins, Minnesota. This week, he’s national news. Here’s why: Joey saw a woman in his store pick up a $20 bill dropped by a blind man. He waited for her to give it back. She didn’t. He asked her to do so, and she refused. In turn, Joey refused to serve her—and gave the blind man $20 of his own money. Thanks to the actions of a customer, a co-worker and the internet, Joey is getting the credit he deserves, including a call from none other than Warren Buffett himself!
