But... after the advertising does its work and brings people in, the customer's experience with the product supplants their experience with the advertising. Try to keep people coming back after you've fired your chefs and decided to only employ part-time cooks, because you believe any idiot can cook a steak.
I think the attitude that labor is qualitatively unskillful or that even unskilled labor isn't critical to the value of a company (where that labor produces the product the company sells) is misguided. Quality often matters in surprising areas throughout the process, as does experience. If people come in expecting a great steak and they get something the busboy tossed into a microwave, they're just going to feel lied to. And rightly so.
