I would be sad to lose my beloved self checkout :( I still want real people and full service lanes for bigger / more complicated purchases, but daily small purchases are much more relaxing self-serve.

Many likely believe self-checkout saves time compared to a cashier lane, but the opposite may be true.

Oh actual cashiers are faster no doubt, but they're almost too fast. They'll spin 15 items through in 3 seconds and I can't check prices or bag fast enough. Once I've paid I still have a minute of bagging with next in line pushing me down and 2 minutes of reading the receipt prices left... in self check out I like being able to catch prices errors as they ring up and have less pressure bagging.
