Filling to a level rather than filling when empty
The difference sounds small and is not. A cleaner who tops up only what looks low will leave a dispenser at a third full, and a busy trading day will empty it by early afternoon. Filling every unit to the same set level on every attendance removes the judgement call and makes consumption measurable, because the amount drawn from the cupboard becomes a reasonable proxy for what the site actually used.
It also removes an argument. When a dispenser is found empty, the question is whether it was filled and consumed or simply not filled. If the standing instruction is to fill everything to a set level every attendance, the answer is straightforward and the conversation moves to what the site needs rather than to what the cleaner did or did not do that night. Removing the argument is worth as much as removing the empty dispenser.
