I read an article recently about how self-checkout will eliminate cashier jobs, so it's a bad things. But that seems slightly hard to believe. First of all, about 80% of the times I've done self-checkout, there's been some error that required someone to come over and assist me. Like I don't put my item in the bag fast enough and the whole thing crashes. And I'm relatively checkout savvy.
But today I realized that as long as there are old people, cashiers will always have jobs. Today when I was at the supermarket, there was an elderly woman ahead of me who was attempting to do self-checkout, but completely defeating the purpose of self-checkout. She needed help with every single item she scanned in. She didn't know how to scan fruits or vegetables. She didn't know what to do when she didn't bag her item fast enough. After three different clerks came over to help her at different points, I went over and helped her through the rest of the scanning process.
Then she was unable to figure out how to pay.
The best thing I can say is that she didn't try to pay with a check or scan in a dozen coupons. But it was an excellent demonstration of why cashiers are needed.
