Drinking culture exists in almost every country around the world because alcohol consumption has become an integral part of socializing in many cultures. However, since different countries have their own beliefs and practices about drinking alcohol, it is better to heed to those different traditions and customs in order not to get yourself embarrassed or even in trouble while you are in a different land. Different countries, for instance, do have their own drinking etiquette, times, places and regulations. In the UK, almost everyone knows that you will be discriminated if you don't buy your round before leaving a pub or bar. In the Czech Republic, it is wise to place your beermat on top of your drinking cup to indicate that you're finished with your drinking. Or your empty cup will get filling up even if you don't want to drink any more. In Germany, always keep your eye contacts with people you're having a toast with. If you don't, you'll be condemned with having seven years of bad luck. In Japan, however, you should avoid offending your colleagues, especially those who are your seniors, by averting your head from them. Drinking times also vary in different cultures. People in the UK, Iceland, and the Czech Republic tend to drink after the midday, in the evening or even after the midnight in the case of Iceland, whereas it is customable for people in Spain, France, Russia, and Germany to drink during lunch. The German even drink on Sunday mornings known as Frühschoppen. It is a drinking gathering for family members after their Sunday morning church service. Drinking regulations also diverge in many countries. Rules about where to purchase and consume alcohol as well as the proper drinking age do differ from nation to nation. In Germany as in some countries, it is allowed to drink in public places while in Russia, people can only consume alcohol in bars, restaurants and their homes. In Iceland and other countries, you are unable to buy alcohol from supermarkets and other grocery stores as it is rigorously supervised. Apart from purchasing it in bars and restaurants, people can only obtain it from government-run vinbudin. The so-called "dry" countries in the world are referred to those nations that treat drinking as entirely illegal. It is worthy of note that in countries like the Kingdom of Brunei, Saudi Arabia, and parts of the UAE and India, people can sometimes get punished for drinking alcohol.
