Cashiers also have their place, for when you have larger checkouts and what have you.

In my grocery stores they've gone so far as making self checkouts with conveyor belts so you can do those large checkouts yourself.

I refuse to use them. If I have a couple small items, then sure self-checkout makes sense. I don't get cost savings, but I do get the convenience of a speedy checkout; faster than the single express lane they used to have.

But I'll be damed if I'm going to be a free cashier for them and scan an entire cart load of groceries and get nothing in return. At the very least pay for a bagger, wtf. Those are the real job killers right there.
