The coffee grinders hung on at several of the grocery stores near me, but got relocated to behind one of the checkout counters. They hung on there for a number of years but finally these got removed as well, along with the option to buy coffee beans loose and by weight. The majority of shoppers probably just bought pre-ground. For what it’s worth, myself and my parents were the only people I ever saw buying whole beans or using the grinders, over the span of decades.

One of the froofy high end grocery stores near me does still offer bulk beans (along with their other bulk products like dried fruit, lentils, trail mix, etc.) but there are no grinders in the store. They probably assume anyone who’s enough of a coffee nut these days would rather grind their own beans at home, and they’re probably right.
