There even might be a disincentive to have garbage cans if they can't be maintained. People who don't litter will either take the extra step of going indoors, or they might leave it in their own car to throw out later. Whereas people who do litter will do so regardless of when there are trash cans. By removing outdoor trash cans, you've "saved" the staff the time to monitor and clear out those trash cans.
Let's move forward.
What incentivized them to provide the trash cans to begin with, might you suppose? They aren't cheap to buy, or to maintain, or to keep emptied daily (or as they fill up, or whatever). But yet: They were things that existed, and their existence was definitely deliberate.
What motivates companies that still provide outdoor trash cans to continue to do so?
But owners are always looking for ways to save money. If the garbage can works fine, it gets maintained. But if it gets hit by a car, or the wind blows it away, it might not be at the top of the list of things to fix. The remnants of the garbage can are removed. The expense gets put off for another month. And slowly the lack of garbage cans becomes normal, and staff can remove another responsibility from their list.
Now the situation becomes, who wants to spend a bunch of money to put in garbage cans, and also add onto the staff's workload? It's not like customers are asking for the manager to install garbage cans.
No matter what, big or small, it's always a Republican's fault, huh.
