Animal-rights charity PETA has urged Starbucks to end its plant-based surcharge* by becoming a shareholder - buying the minimum number of shares to attend and speak at Starbucks' annual meetings.
Currently, the coffee giant adds up to 80 cents to orders that swap cow's milk for soy, oat, almond, or coconut.
'Hard to swallow'
"Many coffee drinkers are lactose intolerant, and everyone should be intolerant of cruelty to cows, which is why charging extra for vegan milks is hard to swallow," PETA said in a statement.
"We're heading to Starbucks' boardroom to urge the company to end this unfair surcharge."
PETA has pressured Starbucks into dropping its non-dairy charge in the past - attracting more than 177,116 people to sign an online letter written by the charity.
"Starbucks should be encouraging customers to choose animal-friendly, vegan milks rather than cow's milk," PETA added.
Many other chains—including Tim Hortons, Stumptown Coffee Roasters, Noah's New York Bagels, Philz Coffee, and Costa Coffee—already offer dairy-free milk at no extra charge."
