Final answer:
The FIRE Report is the best report to show the opportunity dollars lost in running unfavorable labor hours.
Step-by-step explanation:
The report that would best show the opportunity dollars lost in running unfavorable labor hours is the FIRE (Financial Impact on Restaurant Earnings) Report.
This report specifically focuses on the financial impact of labor hours on restaurant earnings. It would provide detailed information on the dollars lost due to unfavourable labor hours, allowing for analysis and identification of areas for improvement.
The other options listed, such as Side by Side P&L, High Risk Coupon Fraud Report, and WEST (Weekend Experience Scorecard Tracker) Report, may be relevant for other purposes, but they do not directly address the financial impact of labor hours on earnings.
