How often should the liner inside a public trashcan be replaced?

We liners live a life of quiet dedication in the shadows of public spaces. Our purpose is clear: to stand guard, to contain, to protect the bin from the messy realities you discard. But even the most steadfast guardian has a limit. The question isn't *if* we should be replaced, but *when*.

Our ideal retirement party depends heavily on our posting. A liner in a serene office lobby, receiving mostly paper, can serve a dignified 3-5 days. We in a bustling café, however, face coffee grounds and food scraps; we plead for a daily change to prevent becoming a sour, odorous nuisance. For us stationed in park bins near picnic areas, a daily swap is non-negotiable, especially in summer. It's a matter of public health, deterring pests and controlling smells.

Listen to us. A heavy sigh (weight), a visible tear (leak), or a pronounced unpleasant aroma are our cries for help. Ignoring these signs risks a breach—a sticky, contaminated bin interior that's far harder to clean. High-traffic locations, liquid waste, and hot weather accelerate our decline.

A consistent schedule is kindness. It preserves the dignity of the space we serve. So, to our human custodians: observe, assess, and act. Your timely replacement is our graceful exit, making room for a fresh recruit to continue the essential, unseen work.
