Green-tinged egg was on Waitrose faces last month when a PR stunt swamped Beaminster in thousands of miniature milk bottles containing money-off vouchers.

"When I looked on their website to see if they have done this promotion before all you get is how they are trying to reduce their packaging for milk bottles," said local resident Paul Rychnovsky. "When I phoned head office they denied all knowledge. They must have spent a fortune. They had people dressed as milkmen and a milk float."
