Why do some restaurants have more staff than they seem to need?
Efficiency is visible when problems stay invisible.
An empty seat is visible. A prevented problem is not.
The hidden mechanism is operational resilience. Restaurants do not hire employees only for normal days. They hire for unexpected rushes, mistakes, illnesses, and countless small disruptions.
Imagine a busy evening where one chef becomes sick or a large group arrives without a reservation.
A second-order effect develops because customers judge outcomes, not processes. Smooth service creates the illusion that little effort was required.
People often think efficiency means having fewer people. In hospitality, it sometimes means having enough people so customers never see the chaos behind the curtain.
