Given the number of pissheads flailing about in the streets, I can only assume that the more enterprising fishermen are bringing in a fuckload of bootleg booze.
They could be secret millionaires of course, but I doubt any of the people I saw were rich enough to be that fucked up. They don’t seem to have the local equivalent of three litres of Frosty Jacks for £4.
Most buy their booze exactly that way or from abroad as they do in most of the Nordics.
However the drink driving limit is very low, a quarter of the UK legal limit and they want to lower it further. Not worth the hefty fine for getting caught, I wouldn’t drink the night before driving personally.
