OP doing the classic “this is a thing in my country/city/whatever and that means it must be the same for the rest of the world” with that title. I’ve never even heard about this before. It’s not a thing in any shops I’ve ever been too, both in my own country and other countries I’ve been to. In my country the only similar experience is when you go to a store and use the machine for recycling cans and plastic bottles, you get a choice to donate the money directly to “children of the world” which is part of a national organisation that works to improve the rights and access to healt care, schools and safety for kids all around the world.
