That's a great and very specific question! Yes, absolutely. In many cities nowadays, you'll find a specific type of public trash bin that comes equipped with a dedicated ashtray on top. These are often called "cigarette butt receptacles" or "smokers' poles.
They're designed with a small, sand-filled or metal cup attached to the side or integrated into the lid of a standard litter bin. The main idea is to provide a safe and convenient place for smokers to dispose of their cigarette butts, rather than tossing them on the ground or risking a fire by putting them in the regular trash compartment.
You'll most commonly spot these bins in high-traffic urban areas like outside office buildings, near public transport stops, in entertainment districts, and at the entrances to parks or public buildings. Their presence really depends on the local city council's policies and budget for street furniture aimed at reducing litter.
From my observation, they do make a noticeable difference. Having that designated spot encourages responsible disposal and helps keep sidewalks cleaner. So next time you're walking downtown, take a look at the trash bins—you might just see one of these handy ashtray tops.
