blue laws or désuétude

Neatorama features an interesting overview of sumptuary laws and practises from around the world that really prompts one to think about the relationship of different societies when it comes to alcohol consumption and how varied those jurisdictions are.
Where and when the sale and imbibing is suffered or permitted has as many or more regulations, regimes and schedules as tax code. From prohibition to the quirky and unenforceable laws, comparing and contrasting the different rules made me think of this mid-century French sobriety campaign that recommends no more than a litre of wine per day, which is debatably désuétudinal—that is, no longer custom and lapsed, obsolete advice. Did you know it is illegal to be found drunk inside a public-house in England? Or that the small-batch absinthe outside of Switzerland is missing rather key ingredients? I can imagine that some of these laws are so codified to encourage domestic consumption and is a matter of pride and patriotism.  What local regulations strike you as odd and byzantine?
