Look, saying “I don’t work here” to avoid using self-checkout completely misses the point. Technology has always evolved by shifting little tasks onto the user in exchange for speed and convenience. It’s not about “working for free,” it’s just self-service - like when grocery stores first let people grab stuff off shelves instead of asking a clerk behind a counter. At the time, some people probably whined about it too, but now nobody thinks twice because it’s way faster and gives you more control. Same thing with ATMs - you used to have to stand in line and talk to a bank teller just to get cash, now you punch a few buttons yourself. Are you ‘working for the bank’ when you use an ATM? No, you’re just getting your money faster without the hassle. Self-checkout is the same idea: a tiny bit of effort, way more convenience. Complaining about it like it’s some moral stand is honestly missing the bigger picture.
Not sure about your lower-than-ideal scanning success rate machines, possibly a location issue. The machines i use work pretty much flawlessly and even if the process itself might be a little longer, the lines are usually nonexistent compared to a cashier.
