In the Netherlands strawberries in the supermarket have generally good quality, and a season too, though you can buy them year-round. But there's only one type of strawberry, the red sweet ones.

A recent dopamine fracking example in the supermarket is beer culture. Couple years ago in NL small breweries were popping up everywhere and making delicious specialty varieties, or reviving long lost beers from old recipes. Also small shops emerged, collecting special beers from around the world. This did not go unnoticed at the supermarket, and the number of brands they offered exploded. Rows upon rows of the most fancy designer cans to attract your attention, highly priced but convenient. It killed off a large part of this trend. "Hey, I can just buy this in the supermarket".
