This seems like a pretty tenuous theory. There's a reasonably solid suspicion when businesses with clear connections to the cube farms, like restaurants and coffee places whose main draw is proximity to offices(and, typically, because of the way the zoning shakes down, significantly less proximity to things that aren't offices) are involved that people no longer seeing them as convenient, because they aren't in the office, or requiring their convenience, because it's a lot easier to make your own coffee when you don't have a commute.
This is a department store though: furniture, clothing, cosmetics, jewelry, housewares of various sorts. Am I claiming that literally nobody has ever popped over in an emergency after spilling coffee on their pants; or that it has never benefitted from being more convenient because it's on the way home from work? No, that sort of thing must happen at least occasionally. Do I buy that people drawn to the area by the fact that they work there are the primary audience for those sorts of (more typically) planned purchases? That seems like a hard sell.
