A Florida woman is in jail on charges she threatened Walmart workers with a gun after the store refused her Internet dollar-off coupon.

Mary Frances Alday of Crawfordville, near Tallahassee, was arrested Friday and charged with four counts of aggravated assault with a deadly weapon and one count of battery, for allegedly ramming an assistant manager with a shopping cart. She was also charged with resisting arrest and battery of an officer, according to the arrest report.

The Wakulla County Sheriff's news release says Alday is 61 years old, but the arrest report states she was born in June 1961, which would make her 51.

Alday became "extremely upset" that the Crawfordville Walmart would not accept her coupon and continued to "verbally abuse" the assistant manager while being escorted out, the deputy's report says. When the supervisor said she was going to take down Alday's license plate number, Alday replied, "If you follow me, I have something in my car for you."

She then emerged from her 2011 Ford Escape SUV with a holstered handgun that she began waving at four employees, who went back inside "due to being in fear for their lives," the arrest reports says. She then backed out of the parking lot and fled.

A sheriff's detective soon stopped Alday and was joined by a deputy, who asked Alday if she had a gun. "Yes, I have a concealed weapons permit, and you are not taking my gun," the arrest report states.

Alday refused to get out of her vehicle, and the deputy twice stunned her with his Taser after she reached toward the passenger seat and continued to struggle. The deputies then pulled her from the SUV and handcuffed her.

The gun — a loaded Smith & Wesson .38 Airweight — was found in the center console.
