Lesson notes
Every time Arthur walked into a restaurant that was in the red, he went after the same thing first: overtime. Left alone it piles up to 20, 40, even 70 hours a week, and almost all of it goes away with simple changes to the schedule. This video also covers closing the front of house with two people instead of four.
Your checkpoint (10 minutes): find your two slowest shifts last week. Divide the labor on each by its sales, then compare that with your labor for the whole week. If your slow nights are way above it, you found your leak.
