Green Loo Rolls -

Where are all the green loo rolls? It has been several months now since green toilet tissue graced the shelves of either Waitrose or Tesco, while a quick look at the Sainsbury's website reveals they offer loo paper only in Aqua Blue, Honey, White, Seabreeze (a sort of patterned affair from the look of it) and Peach Blush. What is going on? Has there been a European directive banning any shade reminiscent of a minor political party in case of unfair influence? Have they discovered that green dye can have a carcinogenic effect on one's nether regions? Answers on a postcard please! Or just email me...
