She ordered a meal at Dunkin' Donuts. But there was a big problem, cops say.

A Florida woman's free fast food binge ended Tuesday.

According to a Facebook post from the Martin County Sheriff's Office, Priscilla Corpus and her alleged partner in crime Jeffrey Scot Robinson was taken into custody on Tuesday.

According to TCPalm.com, staffers at Dunkin Donuts tipped off cops to what appeared to be a fake bill.

Deputies stopped the pair's trek in Stuart as they were motoring to their next location to hit up.

In their car, along with numerous bags of food from restaurants along the Treasure Coast, deputies found more than $500 in counterfeit $20 and $50 bills, along with more than $1,500 in real U.S. currency.

"The duo also had two fake guns, a number of wigs and a change of clothing," read the report.

Corpus, who is from North Lauderdale, admitted to detectives she would go to various fast/casual food chains like Dunkin Donuts, Panera and McDonald's and pay for a meal with a counterfeit bill, then get authentic money in change.

Robinson, who is from Pompano Beach, was the driver, but had no valid license, said the sheriff's department.

Corpus, 21, was charged with uttering a forged instrument (three counts), possessing forged bills and permitting an unauthorized operator to drive. She is being held at the Martin County Jail on a $20,400 bond, according to deputies.

Robinson was charged with operating a vehicle without a license, and resisting arrest without violence. The 19 year old, who was not involved with any phony cash transactions, cops say, was released from the Martin County Jail on $950 bond.
