Korean Culture

I went to Korea with my mother this April. It was a really great trip and I was really enjoyed it because I wanted to go to Korea for a long time. There were a lot of differences between Japanese culture and Korean one.
Firstly, in Korea, almost all of shops serve a guest. When I bought many cosnetics, the shopgirl gave me a lot of samples and some goods of Korean idol. Compared with Japan, the difference is obvious. Moreover, when I went to dinnar, I was surprised the Korean culture still more. The shop girl brought us more dishes than we ordered. We noticed that we should order somewhat below.
Korea is Japan's next coutry and the two coutries are really close but there are a lot of differences. It's a little strange but I think we should respect each other's culture.
