Sounds like they've had a history with customers who order "iced espresso" and then add huge amounts of (free) milk, effectively creating an iced latte on the cheap. They don't want to ration the milk, but they don't want people to rip them off, either, and this is their current solution.

That certainly explains the "what you're about to do is not cool" reaction much better than assuming the barista really hates iced espresso.

The largest-yet observations of this phenomenon that naturally gets larger over time are clustered in the recent past! Shock and horror!

I'm very much a privacy extremist, and I don't mean to apologize for American privacy abuses, but these ratings have quite clearly been distorted to make a point. France, which currently issues national identity cards containing biometric information, scores higher on "identity card and biometrics" than the U.S., which has... outstanding but derailed proposals to do substantially less than that?
