No, fast food has not gone up in price.  This consumer was the victim of overdraft charges.  From the story:

Hickman says the expense resulted from delays in processing her child-support check at the Zanesville, Ohio, branch of Cleveland-based National City Bank. The 45-year-old customer- service representative said she uses a debit card more these days after canceling her credit cards because of high fees.

“I stopped using credit cards to keep me out of trouble and then got hit with overdraft fees,” Hickman said. “It’s not fair.”
