A look around the debris of our urban sprawl is telling. Where there has been trouble, there is broken glass from beer bottles or tonic wine bottles. Empty lager cans roll around the pavements of our blighted towns. Licensed premises are supposed to control the alcohol served to their customers. Isn't it time that off-licenses do the same? The drinks industry could be required to run a license scheme. If you want a carry-out, you can get it only by displaying a license. The license will be issued by the town hall and paid for by a levy on the drinks industry. Any bad behaviour - even a caution - and the license is withdrawn for a month. Good idea or barking mad?
