I run diner and quick-service franchises for a living. Over 14 years I have opened 9 locations and taken a single store doing $840K a year up to a 4-unit group clearing $6.2M.
I hire the crew, set the prep lists, and read the P&L every Monday. My last remodel cut ticket times from 11 minutes to under 7 during the lunch rush.
I still work the line on Fridays. Keeps me honest about the food.
