Picture the scene. ITN’s Keir Simmons is in Sainsbury’s filming a report with money saving expert (and Guardian columnist) Martin Lewis. They need some footage of the bar code scanning machine at work, so the elderly lady who had just finished shopping couldn’t pack her bags. Quick as a flash, the ITV News man helped bag up her shopping, completing it in double quick time. “Do you work here?” asked the woman. “No, I work for ITN,” replied Simmons. “Lovely,” she replied. “I didn’t know they did packing now.” ITV News shopping channel? Could be a money spinner.
