The footage of Juana Martinez confronting the young woman at the Starbucks drive-thru has been viewed nearly two million times on YouTube.
She told INSIDE EDITION: “I couldn't shut up. My husband was nudging me: 'Let's go!' I was like: 'No! I want to make sure the employees see, everyone needs to know what she did.'"
The mother of three said the whole thing started when she got a text from her bank saying someone had used her card to make purchases totaling at $212 at a local supermarket.
She called the supermarket and staff described the woman who had used the card. Juana thought it sounded like the woman who served her at Starbucks the day before.
Juana says she had had suspicions about the girl when the young woman first took her card in payment for a coffee.
“She went to the back with my card. She was nervous to hand me it back. I worked retail for a couple of years so I knew you don't just walk away to the back with someone's card,” she said.
She drove back to the Starbucks near Los Angeles with her husband recording the confrontation on his cellphone. The worker made no attempt to deny the accusations.
The young woman apologizes repeatedly.
The video ends with a pointed comment from Martinez: “You come to Starbucks to get coffee, not to get robbed.”

A Starbucks spokesperson told INSIDE EDITION: "We were extremely troubled to learn of this incident and are working directly with the customer to address this situation. This employee no longer works for Starbucks."
Security expert Robert Siciliano of Intel Security told INSIDE EDITION how to keep your card secure.
"Number one, pay close attention to the card. If they get your card out of sight, that is a red flag," he said. "Number two, download your bank or credit card company's mobile application and sign up for alerts. That way every time a charge is made to your card you get a text message or email. Number three, pay close attention to your statements. The moment you see unauthorized activity, call your bank or credit card companies immediately."
