You apparently have never shopped at Aldi. You need a quarter to get a cart. When you take the cart back and lock it into the carts then you get your quarter back.


That's probably why in the US nobody put their cart back. They would do it if they had to get their coin back. Again, to fight laziness, go for the wallet!


I've been to grocery stores in the US where there's a perimeter sensor that automatically locks up at least one of the wheels of the shopping cart.


And if people won't, there would be droves of people taking the carts and keeping the quarters.
