A cold American convenience store may be delivering the fundamental value at American prices, but there's something to be said about that "extra" human or creative element. One might say the same thing about the changing nature of the web over time, less individual CSS chaos and more Facebook aesthetics.
But I really don't need that quirkiness at Home Depot, the DMV or my bank (or Amazon, or government websites, or my banking site). I'm there to purchase some screws, register my car or pick up some checks. I just need a storefront (or a website) that lets me do that as fast and homogenously as possible.
99.9% of stores (and UIs) are the latter, not the former.
