Neurodivergent people love them. Or at least some of us do.
Going to the store with my wife is one thing, and it's mostly fine. If I gotta go by myself, my AirPods are in, I'm probably listening to Enya, and I'm definitely going for self-checkout if I have the option. I'm tech savvy and I have worked retail (not grocery, specifically) and I'm pretty damn good at bagging. I'm sure I look like I know what I'm doing. If I need help, I can usually wave someone over and they'll get it figured out and it's not that bad. But I'm not there to make small talk, I'm there to get my shit and leave. I know I also have to bag it and pay for it, I have no interest in shoplifting or cheating the store, but self-checkout offers a lot less friction than going through a line. (Hell, when I/we do go through a line, I want to bag, because I can do it better, and I like stores that don't have baggers. Because usually they have a longer conveyor belt and I'm not right in front of the cashier. I'm just doing my own thing.
