You can call it Lavazza intervention. The espresso company and coffee sponsor of all the Grand Slam events this year (the US Open, Wimbledon, Roland-Garros, and the Australian Open) will be letting tennis fans print photos on their cups of coffee through a Ripple Maker, which prints any image or text on a latte. Lavazza didn’t clarify whether fans will get to pick their own designs or will have to choose between pre-set options. It just says people can customize their cups with "special messages and photos, meaning they can support their favorite players whilst enjoying a caffeine kick." The "whilst" is all Lavazza.
