Everybody forgets about escalation. They introduce more dogs, vendors adapt and use better packaging and it is only the vendors with poor packaging and bad service who suffer. I mean, what is it, an extra minute or two to apply another MBB layer and print new labels and designs, but for them that means huge investment in equipment, training staff and sniffer dogs, more paperwork, slower mail processing as customs hold everything up and right now, it just isn't a big priority for the UK given our mail system has possibly the best mail reputation in the world for reliability so in terms of politics, it wouldn't make sense for pressure to be put there.
