Welcome to the world of high finance: Four people who worked with one of last week's Powerball winners are claiming that they deserve a cut of her windfall. The day after winners Pat and Erwin Wales of Buxton, Maine, accepted their oversized check for $41.5 million, coworkers of Pat's at the Lincoln Financial Group in Portland, Me., filed a lawsuit, saying that they were among 19 people who gave her $10 each to join an office pool. A lawyer for the Waleses told The New York Times that Pat had bought the winning ticket separately from the 19 that she purchased for the pool (she reportedly bought 20 for herself and her husband, too), and she has records from the New Hampshire convenience store as proof. In other fallout from last week's Powerball mania, the town of Greenwich, Conn., plans to seek more that $60,000 from the state lottery to cover the costs of handling the Powerball invasion by out of town lottery players. The Associated Press reports that Greenwich is bemoaning the heavy expenses for police overtime. At times, town officials said, one-third of the town's police force was monitoring ticket buyers standing in long lines.
