I get it, I do. I've been a migrant in a place with a language barrier on top of sharing that general feeling, so... yeah, sure. In principle.

But the times I've used it it's twice the anxiety, in that I keep fearing I'll mess up and need help, which is orders of magnitude worse than having to go through the register. Just the potential of issues is enough to deter me, but the times I've had the scales mess up or the payment method not go through were excruciating.
