The Dutch may be best know for coffee shops (meaning the places where you go to smoke weed, not to drink coffee), but the Dutch also happen to be big coffee drinkers.
A lot of socialization (for women at least) revolves around drinking coffee. This is in contrast to my experience in the Britain, where socializing nearly always meant meeting up for a pint of beer or other alcoholic drink. Whereas British cities are filled with pubs, Dutch cities tend to be filled with cafés (for example, the Dutch coffee brand and chain Douwe Egberts).
This can perhaps be explained by the fact that The Netherlands is one of the countries with the highest per capita consumption of coffee in the world. The average Dutch person drinks 150 litres or 7 kilos of coffee per year, which works out to about 3 cups per day.
This is a lot more than most other western countries, which average only about two cups per day (in France, the US, Canada) or one cup per day (in Britain, which is traditionally more into tea). The only countries that drink more than the Dutch are Switzerland, Belgium, and Luxembourg (3-4 cups per day) and the Scandinavian countries, which are the world champions with 4-5 cups per day.
