### Comment:
Sometimes I see Facebook posts about not using self-checkout lines at stores because it’s taking away someone’s job and making the customer do the work. I can’t help but laugh at the idea that we need to “save” all these cashier jobs that are so unskilled and simple that literally anyone can do it themselves with no training or supervision.

### REPLY:
I laugh because they ignore the fact someone has to build that self check out machine, another to program it, another to install and maintain, another to keep the system up to date. You still need a cashier to watch over the machines to help with user errors. Those machines still bring jobs, just a different kind.
