Serena returns money won in gambling
New York: Tennis star and TV actress Serena Williams returned her winnings in gambling recently as she is a Jehovah's Witness and it is against her faith to gamble.
According to the New York Post, Williams was gambling at the casino-themed Rogers Cup gala at the Toronto Hilton.
Williams stayed true to her faith. As she was leaving she gave back all the chips she had won worth around $400 to a stranger at a table.
