I get where you are coming from, and I stand with what you say, but this is a losing battle.

It's cheaper to only have 1 person watching to make sure everyone scans into the the store. Really there is no need to elaborate beyond that point alone. Also it cuts theft because you must scan to get in.

I don't think every store is going to change to this model overnight. It will be gradual over years and years. But it will happen.
