"We wouldn't have known about it if it hadn't been for him," Smith said of the lucky store.
Smith selected a $100 Million Mega Cash scratch-off ticket and revealed a $100,000 prize.
He said his friend was ecstatic to learn his store recommendation had brought him a jackpot.
"He was so excited that the store he picked out for us produced a winner for our group," Smith said.
Smith said he celebrated his win by taking the group out for breakfast.
"I've always fantasized about winning a big prize in the lottery," he said.
The winner said his plans for the money include making home improvements and building a yard fence for his 9-week-old dachshund, Stella.
