Do you do all your shopping in one place?

I came across the following comment by Target's Canadian president in an article on the chain's losses in Canada:

Canadians shop differently than consumers do in the U.S., he added, often buying goods at multiple retailers instead of using Target as a one-stop shopping hub.

So that brings to mind stereotypes of lazy Americans. But then there was this in another article to crush those illusions of superiority:

Even when people are equipped with shopping carts, they won’t endure so much as the three-minute stroll between retailers. Researchers observed that a third of the shoppers at one Canadian power center (the north-of-the-border term for a big shopping outlet) actually parked their cars three or more times during one visit. They just hated trudging across the asphalt desert. It felt ugly, uncomfortable, and unsafe.

Is walking across a parking lot really such a burden? (Obesity epidemic explained?) Reminds me of the look of shock I got when giving a former roommate a lift to the grocery store, when I mentioned that I was planning to walk to another store we both wanted to visit instead of driving halfway across the parking lot.

(On a different note, does anyone other than a developer actually refer to collections of stores as a power center? Funnily enough, Wikipedia suggests that the origin of the term is from California rather than being a Canadian thing).
