The longtime running critique of Starbucks was that they were already an expensive luxury. Why push it and try to raise prices even further? That takes some serious delusion.
It's not what other people think. It's what the Starbucks customer perceives what other people think.
On the rare occasion that I buy retail coffee, it's usually from the Race Trac gas station which has machines that grind the coffee beans and brew it fresh by the cup - nothing to erect a historical statue over, but a solid coffee for a low price.
When Starbucks loving coworkers see me walk in with my ghetto gas station coffee cup, they'll generally mock me for it.
So I suppose you and I each have our own anecdotal data samples, and they apparently vary from each other quite a bit.
