The photos are from peopleofwalmart.com and cover Walmart shoppers from California to Alaska to Maine to Florida. There is even one from Canada.
I am sorry you cannot view this on some mobile devices. YouTube would like you to believe the sign they put up that says, "The content owner has not made this video available on mobile", when in fact I have but they disabled that. So, thank everyone in government and in the corporate level for limiting our freedom.
UPDATE: If you are using an iPhone and go to YouTube.com (not the iPhone YouTube application). You can view this video by scrolling to the bottom of the page and tapping on 'Desktop'. Thank you to 'Somewhatsadistic' for pointing this out!
