The traditional model of grocery shopping in Europe is daily. That's what our grandparents did - as it has been since the Romans invented the urbe and exported the concept around the continent. The famous stereotype of French people biking with their baguette under an arm, is because people did buy bread every day. Then women started working more and more, and they had less time to shop for food, so the supermarkets happened here too - much later than in the US though, because of space and legal constraints. But there is still an attraction for the traditional way of life that keeps a significant amount of smaller and more central stores in business, keeping shopping more distributed: one day you buy fish, the next you buy meat, and everything fits in your bag.
