Alicia Silverstone slams Starbucks over wasted cups, charging extra for nondairy milk

Actress Alicia Silverstone has a bone to pick with Starbucks.

The “Clueless” star went on a tirade against the coffeehouse chain in a series of tweets Tuesday after a worker used a disposable cup to pour her drink.

Silverstone, who is a longtime vegan and environmental activist, said she brought her reusable mug to an undisclosed Starbucks store to “reduce waste.” But she was allegedly horrified to see the staff had used a disposable cup to pour the drink into her personal mug.

ALICIA SILVERSTONE CLAIMS HER SON HAS 'NEVER HAD TO TAKE MEDICINE' BECAUSE HE'S VEGAN

"Depressing! Just brought my reusable mug to @Starbucks &saw staff use a disposable cup, pour it into my mug, then toss the disposable cup,” Silverstone tweeted. “Totally defeats the purpose of trying 2 reduce waste. Then I looked around to see so many people sitting @ the cafe all w disposables! Ugh.”

But that wasn’t her only issue with Starbucks. In another tweet, Silverstone said she was “frustrated” over the coffee company’s surcharge for nondairy milk.

“Y should we be penalized 4 making the eco-choice? It would be amazing for @Starbucks to lead the way &consider enviro externalities associated w the dairy industry by having dairy cost + or at least = plantmilk fees,” she tweeted.

Just when Twitter users thought the actress was done with her rant, Silverstone had one more gripe with Starbucks: “@starbucks one more thing - can you please get unsweetened oat milk at all your locations?”

In response to Silverstone's concerns, a Starbucks spokesperson confirmed to Fox News that baristas are encouraged to make drinks in customers' reusable cups "whenever possible."

"Building on our long-standing commitment to sustainability and an elevated customer experience, we will take this opportunity to review guidance to our partners about personal cup use as we continue to be mindful of waste."

The company also clarified that additional costs are only charged for its alternative milks when they're added to a drink that already has a standard recipe.

"Regarding alternative milks, adding a splash of any alternative milk to brewed or iced coffee, cold brew or an Americano is always offered free of charge," the spokesperson said. "The price of our beverages is based on a standard recipe, so any customizations that are not part of the standard recipe, which could include added flavors, alternative milk, or an additional shot of espresso, will incur a small surcharge."
