Dushane smashed the glass before driving away, and the entire incident was caught on surveillance video, released by the Toledo Police Department.
Her friend said McDonald's shouldn't have let things go so far.
"Had McDonald's handled it differently and just closed the window when it started instead of grabbing her," said Dushane's friend. "If someone dragged me by the hair I'd be furious."
Dushane's attorney said she had been drinking and didn't even remember the incident.
She served two months in jail.
