Wrong.
How do you know ‘they rather deal with machines’?
Change wont happen unless it makes economic benefit. If the Kiosks were more expensive than labor it would not make sense to deploy them, and they would not do it.
It is only because of the increase in labor prices that they did it.
Well, let me rephrase that. Alternatively, from the trend in labor prices they could predict that (lets say) in two years the cost against the Kiosks would be about equal and then start the changes to day, but that doesn’t change the gist of what I said.
YOU.CANNOT.SAY.THAT. You don't know that.
