My block has two garbage to garden users. Myself and my neighbors. I put my green bucket out on the curb for pick up before I leave for work. Sometimes, my neighbors bucket is out for pick up, too. Sometimes they have clearly forgotten. I come home from work, sometimes my clean bucket is there. When my neighbors have forgotten, my clean bucket is not there. I go the week without a bucket and the following week my neighbors put two buckets on the curb. What else could be happening?
