Then they will have to adapt. Here in Denmark we don't have greeters, we bag our own stuff and most of the time we have to put a coin in to get the shopping cart out, which will be returned when we return it. Of course there will be businesses that can't adapt. These will die out and those employees will then, slightly, decrease salaries.
