Robert Thibodaux Sr., 70, said he told Jaime Thibodaux, a cashier at the Shop-Rite store in Thibodaux who is not related to him, that he would return to the store if the ticket she sold him was a winner, WGNO-TV, New Orleans, reported Friday.
Thibodaux said the cashier's error, selling him a power-play option, turned what would have been a $200,000 jackpot into a $1 million win.
Thibodaux said he returned to the store after collecting his money from Louisiana Lottery headquarters Thursday and wrote the cashier a check for an undisclosed amount.
"You made me a millionaire. That being said, I have a check for you," he told the woman.
