Laws around beer reflect cultural norms both in how they regulate and how they express norms that are unregulated. Consider this proposed reform to the hours of sale law of Zimbabwe:

The Ministry of Health and Child Welfare is crafting its own alcohol policy, which might alter the tough proposals by President Robert Mugabe’s health advisor, Timothy Stamps. Stamps has forwarded to Cabinet a policy document that seeks to force supermarkets, shops and bottle stores to sell alcoholic drinks between 6am and 7pm, while the selling of beer would be banned after mid-day on Sunday.

That comes off as a bit odd. Clearly breakfast time drinking is OK there. Here in Ontario, you can't serve a beer before 11 am in a licensed establishment even if you can drink well past midnight. But in each case, you get over 12 hours stretch of imbibing. In Kenya you only get six hours. Alaskans get 21 hours in a row - why bother shutting at all?
