　　I was living in South Korea a few years back when I had to leave the country and return again because of visa restrictions(签证限制). My destination(the place someone is going to) was the town of Fukuoka, in Japan.

I had plenty of money in Korean currency (货币) which I planned to exchange into Japanese currency in order to get me through the evening. Little did I know, however, that it was a bank holiday (a public holiday when shops businesses and banks are closed) in Japan and there was nowhere to change my money.

With no local money, I had little choice but to walk from the airport towards the town while trying to work out what to do. Some hours and a few closed banks later, I heard two young Europeans talking in French, and with nothing to lose, I asked them if they could speak any English. They could. They were students from Belgium, and, after hearing my predicament, offered to put off meeting their friends to take me around the city in search of a currency exchange.

They paid for my bus tickets and took me around several places before finally finding me a hotel that would change my money.
