Sticker shock, a feeling as old as commerce itself, is no longer just an irksome, unexpectedly high bill. In the era of social media, overpaying for dinner is an invitation for anyone and everyone to publicly shake their fist over the health of the global economy.
According to my grocery co-shopper, it tastes a little tiny bit different in an unexplainable way, and this minute differentiation is worth several dollars at a time apparently.
Don't forget that the indiscernable taste is a personality trait and people will inject themselves into your consumption to tell you how inferior you are to touch something not personally vetted by them(no of course they haven't sullied their faculties with generic how dare you).
Double points if it's diet. Your unhealthy chemical vice has to be unhealthy in very specific ways!
