Do you also demand discounts for having a store loyalty card (which necessitates higher prices for everyone else)?
Between these two things, if going to a big-box grocery store isn't the most depressing thing. Notwithstanding the high prices and maybe one staffed checkout lane being open. It used to be that it practically knocked out Boris Yeltsin visiting an American grocery store on the variety and amount of stocked food.
(A perfectly valid demand ...
... incidentally - see, ie., banking - along with all other industries "off-loading" (in essence) costs by making their own customers service themselves ...)
I kinda miss travel agents. They knew some amazing tricks looking for flights.
