I went to Lidl UKs first walk out shop a few weeks ago. You get the bill and receipts about 40 minutes after you've left.

It certainly felt like it could have been sent off to a lower paid country for a human to tot up.

Also consider you're in the store for what, 10 mins - that's a lot of video processing presumably using state of the art CV models. It's quite possibly cheaper to pay a human than rent the H100 to do it.
