The CNN Business has carried an article titled Nobody likes self-checkout. Here’s why it’s everywhere. I don’t blame them, I am one of those who prefer to checkout with cashier than the self-ckeckout outlets, without any obvious reason.

Even during the pandemic self isolation period, I used check-outs with cashier. However, what I don’t get is – occasionally I see a long line in self-checkout when there are plenty checkouts with cashiers waiting for for their guest for checkout services.

According to grocery chain Big Y in 2011, “Self-checkout lines get clogged as the customers needed to wait for store staff to assist with problems with bar codes, coupons, payment problems and other issues that invariably arise with many transactions.” Indeed, I had similar experience when I used couple of times self-checkouts.
