Time: August 2013
Research done: Googled "Saks Fifth Avenue New York women's department", "Saks Fifth Avenue New York layout", Yelp.com's Saks Fifth Avenue reviews. Got this, which indicates shoes are now the eighth floor, and this, which is outdated if shoes are indeed now on the eighth floor.
Questions: What, exactly, is the layout of Saks Fifth Avenue? Which department is on which floor? If shoes are indeed now the eighth floor, does that mean everything that was on the eighth floor is now split between the fourth and sixth? Specifically, our characters are shopping for: men's suits, ties, and dress shirts; women's casual and businesswear, including casual skirts, business-appropriate skirts, business-appropriate dresses, casual to semi-casual dresses, blouses/button-down shirts, and women's pantsuits; women's shoes; and women's jeans/denim.
And can Saks sales staff accept tips without management coming down on them? (Did a quick Google on this one, but experience is probably more telling. Plus, Google didn't really turn up anything.)
