I once saw a video online where a group of researchers tested to see how South Koreans would react in helping a foreigner. They used two foreigners, the job of the foreigners was to play lost and ask locals for directions. One was a white western male, the other appeared to be like an Indonesian male (basically another Oriental with dark or tan/brown skin color). Both played lost and tried to ask locals for directions, both were holding maps, both were dressed properly, spoke with manners, and acted the same. When the Indonesian male sought help from local South Koreans he was largely ignored by both males and females, people literally did not even bat an eye-lash at the poor fellow, as if he didn't even exist, and if I remember correctly probably only one elderly woman came to his help. Then they tested the white western male who played as the lost foreigner asking for directions, the results were in sharp contrasts, many South Koreans took their time and they were helpful and assisted the white western male with directions and advice and even smiled at him.
It was quite disappointing to see how some South Koreans can treat a fellow Asian visitor in their country, I guess it doesn't mean anything.
PS I once had a South Korean classmate and he was a friendly guy, so I know there are some open minded So.Koreans.
