I live in Germany. There are eight different supermarkets within driving distance (less than half an hour), and two smaller markets within walking distance. Two of the big markets have self-checkouts, so I stopped shopping there altogether out of spite.
EDIT: just to visualize the statement, this is one of the cities around these parts (~150k people). Not my actual home as I don’t post personal stuff online, but a good representation of the situation.
Everything within the blue area is less than 20 minutes walking distance away from the blue marker in the middle, and every red marker is a supermarket. If someone dislikes a shop for any reason, it is a matter of minutes to find a different one.
