I remember eating at Sbarro's once upon a time long ago. I remember eating various foods in malls long ago.
Hell, when I grew up even into my college years, a trip to the mall was the highlight of the weekend. You left your air conditioned home, got in an air conditioned car, drove several miles to a giant air conditioned building surrounded by a parking lot big enough to host a traveling county fair.
Though, as this unsustainable economic model has been proven unsustainable, it is no surprise that the businesses that depend on the mall-based, captive audience for their economic success are suffering.
Maybe they'll just blame the President for their economic woes, instead of the fact that their customers are taking their dollars elsewhere for different products in different locations.
