One in five people has admitted to stealing items while going through a self-service supermarket checkout.
It accounts for more than £1.6bn worth of goods being taken from supermarkets each year, according to a survey.
The most common goods stolen through self-service checkouts were fruit and vegetables, followed by bread and cakes, sweets and toiletries.
And the majority of those who admitted taking items said they did so on a regular basis. The survey, by VoucherCodesPro.co.uk, estimates that amounted to around £180 worth of products per person.
