I imagine the 10c doesn't encourage as many people as a +1 public recycling score on one of your social media profiles would.
There are hundreds of unemployed/retired/homeless people who scour parks, and the city centers, collecting these discarded containers and recycling them for the money.
The return rate is pretty high, even with the tiny amount of money per-item.
There is also one woman [1] who for whatever reason chooses to live homeless with bunch of luggage. She doesn't drink at all, and keeps moving from town to town with all her luggage, by walking.
Here's also a discussion about the Romanian beggars you see in Helsinki streets. [2]
