Thanks for guiding me to in English

I am a foreign student who recently moved to Gimpo Gurae-dong. I used to go Itaewon every day by Gimpo City Railway. On my first day, I didn't know how to charge my transportation card or transfer to the subway, but I was able to use it easily because the staff at Gurae Station guided me in English which is quite surprised me , because it’s not easy to find a English speaking korean staff in subways . Thank you very much.
