its like the old saying not paying your road tax . if everybody paid it would be reducedvery good point Paul, hadn't considered bar codes. To be fair, our local supplier is run by a young lady who would struggle to move a cylinder let alone lift the ****** so she says put the empty over there and get your full one from this cage but I guess codes can be read at any time. I think they would probably sell more gas by cutting out the black market merchants simply by not charging such high rental, like mobile phone providers and broadband suppliers, a one off payment and registration. Maybe the old licence style was so abused, it was the only way they could do it.
