Polish millionaire Piotr Szczerek responded after a video showed him snatching tennis star Kamil Majchrzak's hat that he was giving to a child. Apologising to the kid, Piotr clarified he'd thought Kamil was offering the hat to him for his sons, who'd previously asked for autographs. "This...showed me that one moment of carelessness can undo years of work," he added.
