Actually, your assuming that you can pour a margarita and pour the
ingredients in for the next one without stopping the engine then....
(otherwise, your idleing....) You need a clutch and a point you need
to remove the load in order to empty the mixer and re-load....
Otherwise, you'd crank up the engine and shut it off each time you mix
a drink, which would be highly in-effecient....
