Burger King has introduced an AI voice assistant called 'Patty' that sits in employee headsets and listens to every drive-thru interaction. Patty scores workers on 'friendliness' based on whether they use predefined phrases like 'welcome to Burger King,' 'please,' and 'thank you.' The system is part of the broader BK Assistant platform, which both helps staff prepare orders and evaluates their behavior in real time.

Why it matters

This new AI-powered workplace surveillance in the fast food industry marks a shift towards quantifying and automating employee behavior. While Burger King says the goal is to improve customer service, the system raises concerns about the impact on worker autonomy and privacy.

The details

Patty transcribes and analyzes drive-thru conversations in real time, paying close attention to specific phrases the company has defined as markers of friendliness. It then generates a politeness score for each interaction, which managers can view. Patty can also provide employees with recipe information to help prepare menu items. The BK Assistant platform, which includes Patty, will be available in all U.S. Burger King restaurants by the end of 2026.
