Someone's stirring up the Bees Nest about "you" doing the work at Self-checkouts

I've been screaming that for years what's going to happen if people can't use their ATM card to get a gallon of milk for their 2-year-old your average soccer mom and office dweller is going to be freaking the hell out! They won't be able to deal with it
Just before Xmas back in the mid 2000s, I went into a big shopping store ( Target ) and there were a whole bunch of trolleys, filled with stuff, abandoned at the checkouts. The FPos ( digital payment system) had gone down and because people had virtually no cash on them to pay, they just left the trolleys and walked out of the store.
