I have never heard of anyone who has had a bad customer experience with Amazon, Apple, Costco, or Salesforce. The aforementioned companies are incredibly successful due, in large part, to a material focus on the customer experience. Not surprisingly, the stock market has handsomely rewarded these four companies over the past decade.
Amazon is so customer focused that it will literally send you a replacement for a lost package immediately without ever implying that the customer is at fault. The result is a consumer experience that is so optimal that Amazon is the only place where many consumers decide to shop online.
