The self-checkout machine has one word for you: unexpected. Not 'unexpected item' — it never tells you which. It just halts, glowing, like a bouncer who smells something he can't name.
You have now been flagged by a machine you fed coins to. The attendant arrives, taps a screen, waves you through, and you walk away with the deep, unspoken shame of someone who could not simply buy bananas.
The File: The 'Unexpected Item in Bagging Area' prompt has ended more first dates than any red flag ever could.
We rate the self-checkout 7/10 for its commitment to making you feel personally defective.
