There was a time (when I was much younger) that part of the grocery experience was having your cart pushed to your car and your bags loaded into your car.
That time has passed. Now, you’re in charge of your groceries all the way to your vehicle. And you’re in charge of the cart, too – all the way to the return area.
It’s now a high level of customer service if you’re met in the lot by a cart attendant and asked, “can I take that for you?” Turns out, high-level is relative.
