I'd hate waking to Safeway every other day, but I loved doing tiny regular grocery shopping in Europe. It made it easy to always have fresh produce and spontaneously plan interesting meals.
A lot of it comes down to how the cities and grocery stores are designed.
In the US you drive to a shopping mall, navigate through a sea of parking, walk maybe 1000ft of aisles, then spend 5 minutes in the checkout process waiting, scanning, bagging, and paying.
In the European cities I've lived in and visited, mixed zoning means you're likely to have a supermarket near your house or work so doesn't take any extra time to travel to, there's no parking so you just walk in of the street, the stores are about the size of a 7-Eleven so it's fast to find what you want, then the whole checkout process is crazy efficient.
