Some supermarkets here require a token to use. That token is returned on the complete restacking of your trolley

It does well enough at training our population.

They recently stopped using this in the area of Germany where I live. I hate it. People immediately started leaving their carts all over the place. It’s crazy that €1-€2 deposit was the only thing holding people back from being jerks.
I’m in Germany too, nobody leaves their trolleys sitting around.
I’ve seen it mostly at Hornbach and one of the Rewe’s near me, but other places people still return them like normal.
