High street giant Greggs has explained why they have reversed the signs on one of their busiest outlets. Shoppers where the store is in Northumberland Street, Newcastle, spotted the curious sign recently. And Greggs explained it's so people taking photos of a department store's famous Christmas display get their logo the right way round in the reflection off the window. The nearby Fenwick window was unveiled on Friday evening and each year many thousands of North East families queue up to see the displays which are seen by many shoppers as an essential part of Christmas. The ploy also ensures that every photo taken of Fenwick's display will also contain a reflection of the baker's logo, while the mirror-image letting also makes it easier for users to take a proud selfie outside Greggs.
