The businessman was meeting with clients for lunch at Mimi's Café when he noticed the woman. Sitting a few tables over with her 4-year-old boy, she seemed groggy — yet she was drinking a mimosa.

It got worse. The woman ordered a glass of white wine, then another. She was so out of it, the businessman would later write in a statement to police, that she looked ready to fall asleep at the table.

When the woman paid her bill and left the restaurant, the businessman was right behind her, cell phone in hand. When she ran a stop sign in the parking lot, he called the police.

By the time the cops showed up a few minutes later, the woman already had parked at the Chandler Mall, less than a mile from Mimi's. She was buying bath salts when the businessman pointed her out to the cops.

Thanks to the businessman's intervention, Shannon Wilcutt was eventually charged with three felony counts: a DUI above 0.08, a DUI with a child under 15 in the car, and drug possession.

Justice served, right?

Hardly.
