The route is the problem, not the rooms
Both ends of the operation get attention. The display is presented constantly because customers see it, and the back store gets a clean because it is a defined room. The strip between them, usually a doorway and a few metres of floor, belongs to neither and receives whatever attention is left over. It is also where trimmings, water and dropped produce concentrate. Cardboard trays soften in the same spot and add to what sits on the floor.
Naming it in the scope as its own area, with a higher frequency than either end, is a small change with a visible result. It also matters for safety, since that strip is where staff carry crates and where a wet patch is least likely to be noticed. A short pass through it several times a day, by staff or by a day attendance, does more than any evening deep clean.
