Bulgarian likes drinking. They drink a lot, such a Beer, Wine, and Rakia which is popular liquor for Bulgarian. However, there are days when Bulgarian have to endure to drink alcohol. The days are voting day and the day before voting day. People can't order any alcohol in a restaurant. Even Supermarket is not allowed to sell them. In Bulgarian law, voters are prohibited from drinking any alcohol.
I was surprised at that I didn't know why alcohol drinks were covered by the cloth, I couldn't buy Beer. A clerk told me the reason. Do you know other countries which have a law like in Bulgaria? There is no law in Japan. In Germany, I saw election campaign with drinking.
