A West Haven, Conn., Dunkin' Donuts employee didn't take too kindly to an attempted robbery on Saturday evening. Rather than fork over the contents of her register, the young woman struck back, throwing hot coffee in the would-be crook's face and forcing him to bid a hasty retreat.

NBC Connecticut, citing police, reports that the incident began when the man pulled up to the drive-through and asked for change for his $100 bill. The employee, identified only as Angelica, refused. That's when things took a turn for the worse.

The driver attempted to climb into the restaurant via the drive-through window. According to Angelica, who spoke with NBC Connecticut, he said he was committing a robbery. He "tried to get out of his car. That’s when I realized he was serious," she said. "I tried to close the window. He put his arm in it. He knew not to touch, because he knew there would be fingerprints."

Angelica, seeking a way to defend herself, saw the hot beverage she'd made him. "I looked at [it] quick, threw him the first one," she said. "Looked at the pots of coffee and threw the pot of coffee at him. That’s when he started running into his truck."

As the man took off, Angelica dropped an Arnold-esque action movie line: "Go run on Dunkin'," she said, mimicking her company's tagline.

The man drove off in a late-model white Ford Explorer.
