> It's just simple math sometimes where there's so many people with $400+ carts trying to check out and cashiers can only scan so fast. Everyone with medium or small sized carts have to wait in this.

Why don't the customers scan the items themselves as they put them into their carts while at the shelves, rather than waiting until they get to the checkout? That's what we do where I live in the UK.

Stop n Shop in the NYC Tri-State area has this, but they are the only store that I've seen that does. I'd assume it has a technical barrier to implementation, and large-ish up front cost.

Some stores support this; most don’t.
