Sir Paul McCartney is picking a fight with Starbucks over non-dairy milks.
McCartney, who is famously vegetarian, sent a letter to the Seattle-based coffee giant asking them to drop the $.70 upcharge for milk alternatives like oat, almond, or soy.
The ex-Beatle wrote, "I must say this surprised me as I understand that in other countries like U.K. and India, there is the same charge for both types of milk".
He said PETA is launching a similar campaign and is offering his support.
