Nowadays, each super market in Holland uses shopping carts. You may be familiar with this concept. In order to go shopping, you put a 50 eurocent coin in a shopping cart.
This will liberate it from a series of identical shopping carts that are each connected by a small chain. And when you’re finished with shopping, you put it back in such a row of carts and you will get your money back.
Recently, AH, one of the major Dutch super markets, introduced a separate coin for this purpose. You can get it for free at their customer service desk. So you no longer need a 50 eurocent coin to go shopping, you can now also use this particular coin.
Last week I went shopping at AH and needed a shopping cart. A woman was just busy to put her cart back in a row of carts. I suggested to her to give her a 50 eurocent coin in exchange for her cart, saving both of us the trouble to interact with the row of carts. To my amazement, she declined, saying that her cart had the specific AH coin. And she really needed this coin to go shopping next time.
