A pub in Edinburgh has been criticised for installing a coded entry system for its toilets. Only those drinking at the Ensign Ewart, close to Edinburgh Castle, will now be able to use the toilets. Audrey Ollason, who runs pub, said she was forced into the move because hundreds of tourists every year pack her pub to queue for the toilets. She said problem became so severe that regulars and paying customers were unable to use the facilities because they were always full of tourists. Politicians have criticised the pub's decision, claiming it gives tourists an image of Edinburgh as unwelcoming and unfriendly. Tom Ponton, a Liberal Democrat councillor in Edinburgh, said it was "daft and unnecessary". Ponton said: "I don't know how much a system like this would cost but I think it would buy an awful lot of toilet paper."
