I had the misfortune of shopping UK retail for a few years, and especially in electronics, I can't imagine anyone using it as an example of a great way to structure anything, let alone a premium brand like Apple.
The only UK retail brands which don't seem horrible are high-end department stores (Selfridges, etc.) and grocery stores, and neither really seems like a good background for running Apple retail.
