People don't always choose the optimal strategy. How long has monitor technology been available? How long have machines been able to put things into bags ? When I worked in the industry just a few years ago, neither had been widely adopted and they still haven't. You realize that most restaurants still run on 15 year old software? I worked for a place that still ran dos programs.
