Switzerland was the most amazingly friendly place ever. People would walk around with smiles on their faces. This is very different than Korea.
The last time I saw that in Korea was when they were sitting on the top of the World Cup standings for their group in 2002. People would walk around grinning all the time. If you tried smiling at people all the time now, people would look at you like you had a mental problem.
Not only that, but when you got lost in Switzerland, you only had to hold open a map for a minute before people would stop, ask you where you wanted to go, then walk with you to the location explaining the sights along the way. Not only that, but they could probably explain the directions in four different languages.
Koreans have developed GPS devices in their phones, possibly because they don’t want to have to ask strangers on the street directions at any time. They also avoid people with maps most of the time.
It’s the subtle things like that remind you that you are on vacation.
