Why do some restaurants have more staff than seems necessary?
Efficiency is not the same as resilience.
Restaurants sometimes employ more staff than strictly necessary because extra capacity helps absorb sudden demand, reduce delays, and maintain service quality.
A restaurant with extra staff may appear inefficient at first glance.
The hidden mechanism is operational resilience. Restaurants face unpredictable rushes, large groups, staff absences, and kitchen delays. Extra people act as buffers that keep the system stable.
Imagine a restaurant operating with the minimum possible staff. Everything works perfectly until something unexpected happens.
A second-order effect develops because reliable service builds reputation. Customers rarely notice the extra staff, but they remember smooth experiences.
People often think efficiency means having exactly enough resources. In uncertain environments, having slightly more can be the reason everything works.
