I think you have this internal representation of what "going to the store" means which is based on the North American suburban lifestyle of doing everything by car. This is not the model most of the world uses, especially not in old European cities.
Right...I've lived in Vienna and Berlin for over a decade (including a wife and child) and we never owned a car, and generally popped into the nearest supermarket for fetching backpack-sized loot every couple of days.
