Fareway in Iowa does that. They will push the cart to your vehicle and load the groceries into your trunk.
I generally don’t mind self checkout. Biggest issue is produce where you have to determine which of the 14 kinds of yellow onions you have from a picture list where they all look the same.
I was with a friend at Aldi a couple days before Christmas. Went early in the day hoping to beat the crowd. Nope. Got our few items (maybe 12 or 15) then went to the self checkout. He accidentally scanned the hamburger buns twice. Looking around at the throng of people and no available employees, I just told him to grab something else of similar cost and thrown it into the bag without scanning.
Not worth their time or ours to correct something for just a few cents either way.
Next time, just bail out. Wheel back around and start over on a different station. This will transfer the trouble where it belongs.
