I remember last mechanical cash registers in my country in 90s and when these got replaced by early electronic ones with blue vacuum fluorescent tubes. Then everything got smaller and smaller. Now I'm pestered to "add the item to the cart" by software.

Last week I couldn't pay for flowers for grandma's grave because smartphone-sized card terminal refused to work - it stuck on charging-booting loop so I had to get cash. Tho my partner thinks she actually wanted to get cash without a receipt for herself excluding taxes
