Yeah the updated the recipe and changed it when customers got too upset about not getting more milk when they get light ice.

Adding milk to certain things like iced coffee, brewed coffee, hot tea... They're just part of coffee culture, using milk to lighten the drink and flavor. Shaken espresso is much more akin to iced coffee in my mind, especially as it follows the same standards in the build e.g sweetened or not with classic/syrup of choice, 2% milk default/milk of choice. Similarly to an Americano which is an espresso drink altered to replicate a brewed coffee. Pairing milk with coffee is part of coffee and it's culture. Only reason it's a charge with lattes is because the milk is the majority of the drink volume. Even if someone mods a shaken espresso making it seem closer to latte than iced coffee, they ordered and want it that way for a reason, we don't need to police it. Which we can control, along with the way we view things and assume the best in others.
