I worked at a Dunkin Donuts when I was 16 and this is what we did (and does work for drive through). However instead of a ceramic cup we used a normal plastic cup to mix the drink, then poured it into the customers cup. If it was just black coffee then we could pour straight into someones mug. A ceramic cup would be better (because we threw away the plastic cup after pouring). I’m struggling to recall if any drink except the chai tea could be entirely mixed inside the metal cups which are used on the steam wand. I’m not sure if the SOPs have changed in the past 7 years.
