To say that Americans have a shopping problem is an understatement. A quick visit to Costco will show that many Americans truly believe they need to have 24 cans of chicken soup on hand at any given moment. Also, many American pantries look as though their owners are preparing to survive a nuclear holocaust. In Vienna, however, it seems there is always a grocery store within a two or three block radius, the kitchens and appliances therein are smaller, and even the grocery stores and shopping carts would be dwarfed by their American counterparts.
I believe this stems not only from the fact that we are in dorms (and because we are students we don't need a full kitchen), or that we are in a large city (therefore the stores may be smaller to conserve space), but also from the fact that Viennese approach the consumption of food differently. A slower approach to food is evident in every cafe, where the food may take longer to prepare, but the guest is also allowed to linger and enjoy their meal and is never rushed by the waiters (this last thing is a mixed blessing, as the waiters can also be very difficult to flag down).
It seems that here shopping is expected to be done more frequently. This is evidenced in the smaller shopping carts and kitchens. Additionally, this allows for more frequent consumption of fresh food, as opposed to America, where canned and frozen vegetables may appear on dinner plates more frequently than fresh produce.
Milk and other fresh items also come in smaller containers, supporting the idea that shopping is done fairly frequently, and many vegetables and fruits are not refrigerated in the store.
I was shocked to see mushrooms in a shelf rather than in a refrigerated section when I first went shopping. I think this is partially due to the fact that the farms are closer to the grocery stores than in America (for example, most iceberg lettuce in America comes from California) and partially due to the fact that the food is expected to be eaten quickly, therefore it doesn't need to be refrigerated for days I transport, then days in the store, then days at the consumer's house.
I have also noticed that a lot of the packaging is more eco-friendly than in America. For example, the potatoes here come in cloth netting rather than plastic bags. I think this relates to the concern for the quality of food and shows that care is taken from the growth of the food to the purchase, and then all the way to the disposal of the packaging.
Overall, I think the freshness and quality of food in Vienna takes precedence over the quantity and convenience of having a lot of it on hand, like in America.
