I have been to Europe alone in 2010 in summer vacation. It was great time for me.

While I was enjoying traveling, I got some fraud. As soon as I arrived at Swiss. I need to

change the unit of money to franc. At that moment, some guy had approached me, and

said he had 500 bill franc by showing it up, but he had to change it to euro so that he

could move to Germany tomorrow. he wanted to change his franc with my euro.

so I asked him that let's ask anybody about the money whether it's real money or not.

but he refused the suggestion and then he left. But after 10 minutes, he came back to me

again to change money with me. He had done that 3 times. but I didn't accept him.

Because I hadn't seen Swiss money, and he was too suspicious. After I got home,

I asked somebody about that. but the person said there is no 500 bill franc in Swiss

anymore. Lots of 500 bill franc was stolen by someone 10 years ago. so Swiss

government has removed 500 bill franc.  It was my first experience about fraud.
