Call him the Santa Claus of ice cream. A man known only as 'Mr. Gary' spent almost three hours at Sweet Sammies in Fort Worth, Texas buying everyone ice cream on a Saturday night. Owner, Kory Close says he's never met Mr. Gary before. He says he didn't want to ask him why he was being so generous, but noticed the man seemed to have a great time treating complete strangers.
