Cappuccino with almond milk

Love Terbodore coffee at Big Dog Café in Franschhoek. They charge an extra R5 for plant milk, which is commendable, but surely cow's milk users should be slapped with a surcharge?! BD offer almond, oat and soy. Btw, the carrots in the pic are my doggo's snack ... she is a vegan dog with very clean teeth!
