5 of the Most Interesting Customs in the World
Switzerland-Honesty shopping
There are little shops in the middle of the Swiss Alps that allow you to buy your fresh cheese, milk, bread, honey, and butter without anyone to watch you. In fact, no one watches these shops because they are owned by farmers who are out taking care of the animals.
South Korea-NOT tipping
Tipping is in the blood for someone who is raised in the United States along with many other European countries. But in South Korea, employees in the food service industry are given fair wages and take pride in their work, and it is insulting(侮辱人的)to attempt to tip them.
Iceland-Christmas Eve books giving
People puzzle over the eternal(永恒的)question of Christmas gifts. Iceland has solved this problem with the Christmas Eve tradition of giving a book. After everyone unwraps the books, they spend the evening reading together.
Japan-Pushers on the subway
Japan's subway is crowded during rush hours. But instead of settling for the inefficiency that personal space demands, Japan has "pushers". They are exactly what they sound like-employees whose only job during rush hour is to push more people onto the train.
Russia-Offering vodka
It is the custom to welcome new friends with shots of vodka. What better way to break the ice than with some stomach-warming shots of this Russian tradition? That's something we can all toast to, or, as they say in Russia, "Na zdorovye!"
