The proliferation of self-service checkouts is gathering pace. Whilst any kind of staff-based cost saving was always going to be a winner with the retailer, there is now an opportunity for a visceral kick out of cheating the system in tiny ways e.g. holding one of the apples just off the scales whilst it is trying to weigh your fresh produce, entering a wildly inaccurate number of plastic bags used and of course, la pièce de résistance, placing an unexpected item in the bagging area.

I like that :)
