The same floor, three different soils
A single unit running a service or repair activity, a storage function and a customer counter produces oil or dust, packaging debris and ordinary foot traffic soil across overlapping ground. Cleaning it with one method spreads the worst of the three across the other two, and the counter area, which matters most for the business, receives the consequence.
The workable approach is a short activity map: where the messy work happens, where stock moves, where customers stand. Each gets a method and, in the case of the messy zone, its own equipment. The order of work runs from the customer area toward the messy zone, so the last thing disturbed is the dirtiest. Recording the map on a single page and leaving it with the occupier also gives them something to update as the business changes.
