To help the present situation – I bought a consignment of toilet rolls cheap from a well know auction site. When I received the package there where only half the number of rolls that I expected. I connected the seller and told him – he sent a message back asking if I had unwrapped one of the rolls. I hadn’t but I was curious to work out what he was trying to tell me. When I took the wrapping off and unrolled a few sheets I read the printing on each sheet – it said “Please use both sides”
