Last week, I went to a supermarket called Maxi.
At Maxi, you have to put une piasse (1 $) into a device on le panier (shopping cart) to release it from the other ones. The panier only accepts one-dollar coins.
When I had finished shopping and returned my panier, two women approached me. One of them asked if she could take my piasse in exchange for four quarters so that she could take a panier.
Est-ce que je peux prendre ta piasse pour quatre vingt-cinq sous?
Can I take your loonie [one-dollar coin] for four quarters?
I took a photo of the sign so that you could see it and learn French vocabulary from it.
Some of the vocabulary on the sign includes: dépôt, se procurer un panier, retourner le panier, magasiner, passer à la caisse, déverrouiller un panier, monnaie, jeton réutilisable.
I found another sign that uses the word panier on it at the entrance to a store called Dollarama.
On this sign, shoppers are told to use a panier (basket) when shopping in the store, and not one of their own sacs réutilisables, reusable bags.
