I'm old enough to remember my DM and DF talking through whether what we were bringing back to the UK from our holiday abroad meant we should go through the "anything to declare" exits. This was by car at ferry or hovercraft terminals and we'd have lots of food fags and booze.
Plus the limits on what one could bring home when flying - 200 cigs and a bottle of spirits if I recall.
Come Brexit, will these be restored?
