Milk design?
Suddenly I have this image of people with stirsticks making pretty patterns in lattes. Surely this is not what you mean.
No they don't use sticks, or well, they might.. but it's how they pour the milk in from the canister and make a fancy design on top. Again, why does this job exist?
Red, anyone can make coffee. The machines do the work. This job is specficially for making the coffee look pretty. You make as though these people are hand grinding the beans, etc. All they do is a push a button that says "Start". Oh wait, they also fill the machine with coffee and water.
