Fast food fans have criticised pizza chain Domino's after a staff member - wearing his Domino's uniform - was spotted buying a large quantity of potato wedges in an ASDA supermarket.

The worker was photographed putting around 15 1kg bags of the seasoned wedges, priced at £1 a bag, through the till.

The photo was uploaded to Twitter by SineadSarahxo, and to Facebook by Suzanne Fraser, on Sunday afternoon, going viral on both social networks.
