When machines provide better customer service

I’m intrigued by McDonald’s move in Europe to replace some cashiers by introducing touchscreens on which customers can order their own food because it is a practice that could be introduced more widely in retail outlets and restaurants.

My reaction stems from having noticed that I prefer to use self-scanning machines at a local supermarket rather than go to the aisle where items are scanned by a cashier. I find it generally quicker and easier to scan them for myself.
