Refuse to do free work for a company—insist that the grocery store employees go and gather the items on your list from the shelves for you! Never set foot on the sales floor, do pickup orders online only!
Background: It used to be that the proprietor of a store brought items you requested to the counter for you. In 1916, Piggly Wiggly pioneered a new grocery store model, requiring/allowing the customers to pick items off of the shelves themselves. Not only did they not give you a discount for doing their work for them, they raked in more money from impulse purchases. The increased sales more than offset the increase in shoplifting losses. A cynical, corporate ploy to bleed customers dry, and we just think it’s normal now!
That is to say, the purpose of a grocery store is to provide food in exchange for currency. There’s no law of nature that I know of that says that having an underpaid teenager drag your food across the scanner is the only proper way to do check-out, just like there isn’t one that says only a store employee can pick items from the shelf.
And, eliminate Euclidean zoning in the U.S., so that people can live near where they work, or work near where they live. (Not all of us can do it, or like working from home.)
