alt Hacker NewsAnd the self service kiosks/checkouts at supermarkets. So infuriating! Like I'd have to try to make something that slow myself on purpose!
Besides the fact that scanning a barcode seems beyond much of the general population, they do it so sloooow.

The self service kiosks are intentionally throttled when scanning barcodes, at a guess to prevent people accidentally scanning the previous/wrong item - I once had some problems with one and a staff member flipped it into supervisor mode at which point they were able to scan at the same rate you'd see at a manned checkout.

Some of these are just dumb terminals with the entire state handled on a server. I've seen a bunch of them freeze at once where no UI would respond (but the interactions were buffered) and then when the network hiccup was over they all unfroze and reflected the input.
