I always use self-checkout and apparently so does everyone else.
I never use them. They do NOT save time.
I hate self checkout. If they want to give me a 10% discount in my bill for doing someone else’s job I might consider it.
At our Walmart they installed a huge number of self checkout lanes, which lasted for about a year. People hated and avoided them. Then they put it back to the old way.
I’ve heard that it’s easier to start using those lanes, but IDK if that’s true.
