The cupboard tells you more than the floor
A floor cleaned two hours ago looks the same whether it was cleaned well or quickly. The store cupboard does not. Cloth condition, whether the soiled bag reflects the areas worked, chemical labelling and dilution, machine condition, consumable stock and whether anything has been left where it should not be. All of that describes how the site has been worked across weeks rather than in the last hour.
It is also the fastest check available. Five minutes in a cupboard will tell an experienced supervisor whether the site is being run properly, and it points directly at what to look at next. If the cloths suggest one bundle is serving the whole building, the amenities are the next stop. If the machine is filthy, the floors are worth a closer look. It is the closest thing to a diagnostic tool a supervisor carries.
