As a frequent shopper who's navigated countless supermarkets, I know the frustration of forgetting change for the trolley. No coin or token? No problem—skip the line at customer service with this reliable trick I've used for years.
I often forget a coin or token, forcing me to make change or beg at reception—a real time drain.
Thankfully, there's a simple, effective solution: use an old loyalty card. Here's how:

1. Grab an old loyalty card from your wallet or car.
2. Fold it widthwise to snap off a 2.5cm-wide piece.
3. Slide the piece into the trolley's slot.
4. Pull the chain to release the trolley effortlessly.

You've now got your trolley without needing tokens or change. Quick, easy, and foolproof!
This works across major chains like Carrefour, Leclerc, Auchan, and more—far better than hunting for 1-euro coins or 50-cent pieces, or queuing for a token they might not have.

- Remove a round key from your keyring.
- Insert it upside down into the slot, mimicking a 1-euro coin.
- Its size matches the token perfectly, releasing the trolley.
- After shopping, simply retrieve it like a coin.
