"Stores were nominated by consumers and trade executives and then visited by 'raters' from Franklin (Franklin Resources, a retail merchandising company), who purchased footwear and then completed the evaluation form."
TRANSLATIONS
Consumers & Raters = folks who actually filled out questionaires and "secret shoppers". Their experience dictates the rating. So, if they got a great fit, big smiles, loads of patience, and felt comfortable - great score! If they got pseudo-surly college kid / local elite who talked only about himself, store felt clubby, poorly merchandised, dirty, had poor selection of sizes/SKUs or they were made to feel "fat and slow", "not worthy", or "intimidated" - poor rating.
Trade Executives = sales managers and reps. Is the store easy to work with, humble, growing, buys whole lines, pays bills on time, doesn't ask the company for too much? Then it rates high. If the store owner / buyer is a bastard, returns stuff he won't sell, cancels orders a few days before shipping, constantly whines about everything while suggesting he knows more than the shoe company ever will, talks crap about companies to other owners / franchisees, constantly in credit jail, always wants more discounts and/or free stuff? Then it gets a low score out of spite.
I don't know the store in Minnesota but I do know the industry is very interconnected and the store's and retail chain's reputations are well deserved and quite universal amongst the manufacturers.
