shops like these are obvious fronts for money laundering. Anyone who walks down Oxford street and sees all the sweet shops will know what i'm talking about. Another example is how, apparently the number of barbers in the uk has doubled in the last 10 years. The authorities are being staggeringly incompetent in dealing with it. Maybe they can't, or maybe they don't want to because these shops are keeping the high street from dying (just to be clear that's not a good excuse).
This fits in to a wider pattern of authorities in the uk taking no meaningful action against the people who bring over illegal migrants over the channel, and against grey market companies who block book all the driving tests in the entire country and probably in many other areas.
At least i haven't heard about major benefits fraud. Maybe thanks to Universal Credit, or perhaps i just haven't heard about it.
