For me, chained together shopping carts took some getting use to.
I don't know about you, but Wally-World didn't make us put a coin in a slot to be able to use a buggy. Maybe they do in your area of America, but buggies were free where I came from.
Well, there really isn't a charge for the cart unless you don't return it to it's rightful place. There, you can chain it back up and out pops your coin.
In Europe, our smallest paper money is a five. So we have coins in all varieties including a 50 cent piece, a 1 Euro and we even have a coin for 2 Euros.
Most buggies will accept a 50 cent coin. (= 72 American cents) But some only accept the 1 Euro coins (= $1.43) So if you choose to not return your buggy to it's proper place, you're throwing away that money. And the lucky guy after you will gain it!
(Just a few of the many coins we use. Even men carry change purses. )
However, most families here shop frequently, so they only have a few items in their buggy. They remove their sacks (which we pay 3 cents a piece for in most stores) and can leave their buggies in the receptacle on their way to their car. Eliminating the need to walk three isles over to return their cart.
Some business give out these nifty little things. Plastic money.......
Somehow, I had a hard time making sure I always had coins in my wallet for buggies. But with these little boogers that's no longer a problem.
So what about you? Do they chain up the carts where you live?
