Vish I think your example part NI container part Republic is a bit far fetched I can't see that being a major event almost all goods to Northern Ireland come via mainland Britain. There may be part containers but it's very small beer and in any case the split container can be bar coded and allocated via software just as if it was a full container we are in 2018. Also not every container is checked they are sample checked and remember Northern Ireland is a small rural economy as is the republic we are not talking say Britain vs Germany then I could see your point
The Republic is a small rural economy.
That would be the same Republic with the fastest growing economy in Europe. An economy driven primarily by the activities of multi national companies who operate there.
Will you ever stop making things up just to suit your argument. It is embarrassing
