They expect me to do free labor

I’m pretty sure people were complaining about this when supermarkets replaced greengrocers. “What do you mean I can’t just hand a list to the clerk and have him package up my groceries? They expect me to do free labor?” But we kept it around because the convenience was worth it.

for a huge evil corporation,

The smaller evil corporations use them too.

but give me a scanner far worse than they give their paid employees,

I don’t know where you’re going, but at the grocery stores I go to (and the one I used to work at) the scanner is literally the same unit as on the checkout the human is operating because that way it’s easier and cheaper to keep parts on hand to fix them.

which scolds me every 10 seconds for not having enough space to put things.

HONESTLY this is like the ONLY JOKE people have about self-checkouts. You could joke about the thing always being out of bags, or having trouble when you’re trying to buy alcohol, or flagging down an attendant when the thing doesn’t have a barcode, and yet everyone chooses “unexpected item in the bagging area,” which hasn’t been a problem for people who actually know how to use the thing for a decade or more? Why is this the mindvirus that has infiltrated everyone and not, like, social equity?
