Will the customer pay an up scale price for a mixed drink if the bar tender's role has been reduced to simply pressing a button?

I think Starbucks found this out a number of years ago when they were experimenting with their pre programmed espresso machines.  It does, however, reduce the training time, increases the consistency, and allows what was a skilled position to a more entry level task which potentially lowers the wage required.

Starbucks has a self serve machine in some non traditional locations.  Very surprised at the quality of the beverage when compared to one of their regular locations.
