If a boxer holds an open workout, then it is his responsibly to the fans to make sure they all get to experience something, otherwise why bother. He should have presigned some photos and had them handed out after. He could have signed 750 photos before he left his house, it wouldnt have taken that long. He could ave signed them over a 5 day period if he didnt have much time. But, he chose to have an open workout. If his fragile hands couldnt handle it, then he shouldnt to puplic apearances at all.
