If you want to change the working model a store uses, buy the store and change it. What you’re experiencing here is getting older and hating change, which is fine, but you’ll not stop progress. The self checkout as it is presented today is part of a process, where a need is discovered and a new process implemented. The next step will happen when technology and common sense revises it to the point that it truly is more convenient. The old style gas pumps were complicated, and the push back just recently ended in the last hold out state, yet here we are not thinking a thing about pumping our own gas. Things change and we have to adapt. Technology has always killed jobs. It provides them too, it’s a trade off, ask any wheelwright or typesetter. Understand that a significant portion of our children in school today are going to take jobs doing things that don’t even exist yet. Instead of pushing back at grocery store models because of technology and change, get behind schools teaching our children how to learn new things, instead of living in the past, help plan for our children’s future.
