I encounter “Self Checkout” at least once a month. In my opinion, the self checkout lanes are designed to be an extension of the 15 items or less idea. They are for people who only have a few things and are looking to get in and out as fast as they can. It seems that most people agree with this. It’s become a social contract. However, every once in awhile, I encounter anarchists who don’t feel this way. They take a full cart with alcohol through the self checkout, then get annoyed when people are annoyed with them. These are also usually the people who don’t understand how the screens work and get confused that they need to show ID to purchase alcohol. They are the ones that Garfunkel and Oates had in mind when they observed that “if her IQ were 5 points higher, she’d have low self-esteem.” I just wanted to buy bread and go home, but now I have to stand here and watch your life collapse into public disaster.
