They stop doing it often because it gets homeless people coming to the store specifically to return carts that people didn’t return so they can collect the refund.
“Oh no, we accidentally provided an opportunity for homeless people to make some money! This must be stopped IMMEDIATELY.”
I really don’t think it’s the reason where I live. People just return the carts in general and we don’t really have homeless people as a visible issue
I would hope someone realized it accomplishes nothing except being a mild annoyance for customers. Most people return the carts anyway and it doesn’t really stop anyone from stealing them if they really want them (or rather buying them for ~1 euro).
I’m not so sure. It’s a really small push but people from places where it exists only in some places and where in others they don’t return the carts it seems to be working. Here they are returned, but we are so used to the coin system that it might be leftover from that. Anecdotally I’ve noticed people leaving them wherever more if there’s no coin system. But also my area has a lot of first generation and very recent immigrants so they might’ve never been with the system to begin with. Or it’s a cultural thing. Dunno. Might be all the reasons.
