Your prior should be that after Amazon acquires a company and Amazon "leaders" make their way into the corporate structure, that company will go downhill in terms of any customer-service differentiator. cf Zappos, Whole Foods, etc.

The differentiators - usually reflected in motivated staff with the freedom to solve customer problems, but also in the case of WF a focus on quality fresh food, etc - will be relentlessly driven down.

WF continues to be "premium" but it's definitely not the same chain that it was a decade ago.
