SAN JOSE, Calif. (MCT) — When Emily Leach stopped by Liquor & Tobacco, a convenience store in the San Francisco Bay Area community of Mountain View, before Friday’s drawing for the California state lottery’s Mega Millions Jackpot — then worth $290 million — she was already a kind of celebrated figure at the store after winning $1 million on a lottery ticket she bought there in January.

Her recent good fortune allowed her to perform random acts of generosity for strangers, so it wasn’t completely out of character when Leach offered $100 to one of the men waiting in line behind her as she turned in an armload of Scratcher cards. During that transaction, she either unintentionally handed the stranger a Mega Millions ticket she had just bought, or made him the lucky recipient of some truly astounding generosity.
