MINNEAPOLIS (AP) — Joey Prusak was appalled when he saw a customer at the suburban Minneapolis Dairy Queen store where he works pick up someone else's $20 bill and slip it into her purse. So when the woman got up to the counter to order, Prusak refused to serve her unless she returned the money. When the woman refused, the 19-year-old store manager went a step further: He gave the visually impaired customer who hadn't realized he'd dropped the money $20 out of his own pocket.
