As an ex-publican,I think that you are right,the EU will not leave it at that. In a few months,this will rear it's ugly head again and it will go through. We all know what that means,more pub closures,more people out of work,but,no significant difference in the drink /driving convictions,hardened drinkers will only stay the same. Of course we will have the temperance movement saying it's a good thing to have a zero limit,we know it's all about control of the masses.
Anyway,a wag at my last pub,a bit of a comedian,remarked on the labels of the local brewery (Tolly Cobbold)showing a picture of the brewery alongside the River Orwell.He said something was missing and that was a couple making love on the riverside sand,implying the beer was phucking near water!!
