Joey Prusak was 19 when he was working at a Dairy Queen in Minnesota, saving for business school. One day, he noticed a visually impaired customer drop a $20 bill without realizing it. Before the man could notice, a woman behind him picked it up and quietly put it into her own purse instead of returning it.

When she stepped forward to order, Joey confronted her and asked her to give the money back. She refused, insisting it was hers. After a second refusal, Joey made a firm decision: he would not serve her unless she returned it or left. The woman argued, shouted, and eventually stormed out of the store.

Joey then walked over to the blind customer, who had no idea what had happened, and gave him $20 from his own pocket. He didn’t tell anyone or try to make it public. He simply went back to work, treating it as the right thing to do in the moment.

A witness later emailed Dairy Queen praising Joey’s honesty, and the story quickly spread online. It reached Warren Buffett, whose company owns Dairy Queen, and he personally called Joey to thank him. Soon after, Joey received donations, job offers, media attention, and recognition from strangers who were moved by his integrity—all because he chose to act when most people would have stayed silent.
