In Spain you have to use a coin to detach a cart from the others.
Well, I have a homemade metal thingy than can release the cart without a coin AND I can pull the thing right back out so I don’t even have to leave it in the coin slot.
When I’m done I still leave the cart in the return area and attach it to the others. I don’t even leave it unattached for the next person, because some pieces of shit already leave carts around the parking lot somehow.
I’m a petty motherfucker and I wish the worst to those assholes.
