Unexpected item....

Hardly surprising that the supermarkets report that their self-service checkouts are a magnet for shoplifters. Even over 20% of those who use them admit to not paying for items they have taken through, although not all have done so intentionally.  I suppose from the supermarket's point of view it's a simple calculation - which costs them more, the amount they lose through shoplifting at the self-service checkouts, or the amount they would have to pay to employ real people to man the same number of traditional checkouts?  I reckon that the fact that the self-service ones are still there - indeed in my experience they are increasing in number, means that they have made their choice.
