In this image taken from video shot July 18, 2012, Seth Collins talks about leaving a $500 tip for 21-year-old waitress Chelsea Powell at Bella Notte restaurant in Lexington, Ky. Seth's brother, Aaron Collins, who died on July 7, left instructions in his will to leave a $500 tip for a server. Since Collins' July 7 video of him telling his brother's story and handing Powell the cash went viral, donors inspired by Aaron's dying act of charity have contributed $47,000.
