I'm sorry, I'm really missing something, maybe because I don't carry a purse.
Walk out of the store with your groceries in the cart.
Get to your car, unlock the car, put the groceries in the car.
Close the car, lock the car, return the cart.
Return to the car, unlock the car, get in.
Yea, ok, returning the cart is an "extra step". And I guess locking the car back (although if you put groceries in the trunk, you just close the trunk) is a huge hassle.
You said "Perhaps that's (the purse being stolen) is why no one does it (returning carts) here." So yes, you listed purses being stolen as a reason people don't return carts.
And
@VandVsmama, I'm not sure what judging you're seeing here.
