What is the real cost of running a business without a shopkeeper?
A shop without a shopkeeper does not lose money in one big way. It loses it in dozens of small ones: missed greetings, unanswered questions, skipped upsells, drift in inventory, decline in repeat customers. The total compounds quietly until growth flattens. Most leadership teams diagnose the symptom as a marketing problem. The actual problem is that no one is tending the floor.
