Starbucks in Japan has reduced the amount of drip coffee it pours into a cup by 9mm (about 0.35 inch). A short drip coffee is now filled to 15mm below the top, whereas previously the surface of the coffee was 6mm below the rim. The price isn’t any lower, though.

Wonder if that equates to 2% inflation? Gotta be close, right?
