They cheered, snapped selfies, sipped Slurpees and video-chatted with relatives as far away as India.

A day after it was announced that a Chino Hills 7-Eleven sold California's sole winning Powerball ticket, the convenience store was still swarming with excited customers, local politicians and lottery officials Thursday.

Amid the crush of celebrants, the office manager of a nearby tax-preparation service seized the moment to promote her business, handing out fliers for a $1,000 giveaway. "We feel like we're all winners because it's in our community," said the office manager, La Dawna Magnotte.

In the weeks leading up to Wednesday night's drawing, the jackpot had grown to over $1.5 billion, triggering a nationwide frenzy of ticket-buying.

On Thursday, convenience store owner Balbir Atwal spent the morning granting interviews to reporters and greeting happy customers.

"Everybody's come here to support us," he said, grinning. A sign that read "Millionaire made here," had been hung behind the register. Cashier Rea Paras said people had been buying lottery tickets all morning. "It's just crazy," she said. "They say, 'This is the lucky store.' " Chino Hills Mayor Art Bennett swirled among the crowd.

"I'm just here sharing the story of how proud and thrilled we are that this happened in our community," he said.

Bennett watched on TV last night as a crowd of people rushed the store after the name of the shop was announced.

"That's the funny thing," he said. "The people out celebrating weren't the winners. They were the losers. But they were still thrilled that something like this happened in our community."

Councilman Peter Rogers, who joined Bennett at the store mid-morning, predicted the 7-Eleven would become "a destination."

Both men said they'd bought their own Powerball tickets at a gas station across the road. "I won nothing," Bennett said.

Customer Rita Doerner, 75, came from her home in nearby Chino on Thursday to buy a Powerball ticket at the store.

"I told my husband ... I gotta go see if I can buy a ticket," she said. "I just think it's great. Especially because it's Chino Hills, not Beverly Hills or L.A. But right here in our backyard."

She held her newly purchased ticket in her hand. If she wins, she said, she'd give mo st of the money to a children's hospital.
