FOUNTAIN INN, S.C. -- A Burger King restaurant made a king-size mistake that has caused a royal headache for a South Carolina woman.

A restaurant worker accidentally charged her more than $8,000 for a meal, reported WYFF-TV in Greenville, S.C.

Now the restaurant is trying to correct the error.

The mistake happened at a Burger King location in Fountain Inn, S.C., on Thursday of last week.

Guadalupe Pequino bought $8.64 worth of food at the drive-in window and paid with her Visa check card, issued by Bank of America.

Because the total was entered twice, Pequino's receipt showed she was charged $8,648.64.

The restaurant general manager, Jimmy Gadagno, said workers immediately took steps to credit the account.

"It was an honest mistake, and the store has done everything it can to credit the account," Gadagno said.

Gadagno said the store got a reference number indicating the money was returned to the account on Sunday, but Pequino said it took until Tuesday morning for her to get her money back, the television station reported.

"It's caused her a lot of problems in paying her rent, paying her car payment, buying food," Pequino's friend, Richard White, said. White spoke for Pequino, who does not speak English well. "It's caused a lot of problems. I don't know too many people that can have $8,648 withdrawn from their account and carry on normally."
