Folks, this was on MSNBC (granted the Entertainment/Gossip area), and yes, they refer to it as a "scandal".
"De facto Starbucks spokes-twins Mary-Kate and Ashley Olsen might have a scandal on their hands. A former barista from the Olsen’s oft-frequented Starbucks in New York’s West Village allegedly used to swap out skim milk for the full-fat variety when the girls came by for their caffeine fix...
...one fellow latte-lover close to the Olsens (who requested anonymity) said that she sympathizes with the twins — to an extent. “It’s also my worst nightmare — that and getting a huge diet fountain soda that is mistakenly regular Coke — but I can def(initely) taste the difference"
Yup, I'm done. Goodbye world.
