Perhaps for high-end places where the human touch is important. But for your run of the mill, fast food and cheap chain restaurants, hiring staff is a liability, if you are forced to hire the kind of staff that is willing to work for $8/hour. I've never decided to frequent a particular establishment because their staff was better than average, but there are a lot I won't go back to because they had awful, incompetent staff. Average here means that they deliver something vaguely resembling what you asked for, within a reasonable timeframe, and they can total the order up on the cash register without over or undercharging by an order of magnitude, or crashing the entire POS system of the restaurant. That's rarer than you might imagine...
