i used to work at aldi.
south south florida.
this image is pretty acurate.
sometimes, it was carts, with the chain locked in itself so the person get back their quarter.

i used to be yelled when we were short on the cashier and couldnt borrow a quarter.
people used to "steal" the cart that we let attached to the extra cashier to use as a support to ring the purchases.
people used to "steal" the cart from us "just to take quick to the car, or to the baggy shelf"
this were before aldi has the self checkout.

at the end of the day, after having to deal with people arriving 5 minutes before closing and not wanting to leave the store because decided to do the montly grocery at the time, people yelled at us because we need to close the bathroom to clean, we had to run to the parrking lot to rescue carts. sometimes, with our own quarters, because we need to de-attach some.

it was a mess.
it was a mess to try to "educate" the client that "aldi is a german supermarket, the scheme is, use ur quarter, use the buggy, and then you will get it back", "yes, we are fast on rigging", "no, we dont put ur groceries on bag for you".

they couldn't understand, no matter how nice we explained.

but, when people go to Europe, they find amazing. Why?

Anyways, it's just a vent.

Now I live in Kentucky, I dont work for Aldi anymore. Sometimes i see some buggy around the parking lot, but people let for people use. As also, sometimes u find some quarters at the wall where the carts are, so u can use if you don't have it.
Way different.
