A small task with a real cost and no owner
Moving bins to a kerb and returning them takes only a few minutes, but it happens on fixed days that rarely align with a cleaning attendance and it has to happen whether anyone is available or not. That combination is what makes it awkward. It is too small to justify a dedicated visit and too fixed to fit around a schedule set for other reasons.
The usual result is that a ground-floor occupier does it, indefinitely and without acknowledgement, until they leave or decide they have had enough. The scheme then discovers it has a task nobody has budgeted for and no arrangements to cover. Deciding it deliberately, whether that means including it in a service or asking an occupier formally, is far easier than discovering it in a week when nobody does it.
