Nordstrom Rack

Shopping at nordstroms rack for a bra. I am a taller woman, not to big, though a bigger body requires larger sizes. Why on earth would the store feel it best to put all the small and extra small sizes on the the top of a 3 tiered round rack and large on bottom? I was literally laying on the floor looking for something I like while the smaller petite lady had her taller friend looking for her. This makes no sense
