Supermarkets crucially already have a customer support infrastructure and you can physically go to them to work out issues. If the burden is simply to have human customer support you can speak to then the burden is already fulfilled.

It is absurd that it is impossible to speak to a human at Google unless you have a loud enough platform. Amazon is similar too in many cases. As an Amazon seller the robot once decided that the price for an item on sale wasn’t correct. I told the robot it was in fact correct. The customer support person who I was able to reach after an incredible runaround told me through text only communication that the solution was to change the price either higher or lower. There was no way they could manually verify it. The robot had decided. In the end it took multiple guesses of adjusting the price to figure out what the Amazon robot would accept. This is beyond stupid.
