Friendship or networking?

Laurent suddenly contacted me at 9pm+ to seek help for his African friend, who is trapped at the HK airport with only 20RMB in his pocket, without eaten anything for 1 day... You know this world sucks if you have a friend in the grass root class struggling everyday for basic survival (I'd view it this way :p), and so do his friends... If I was in HK, I'd definitely help him to contact the airport or the immigration office. Will I travel to the airport and give this stranger money? This is a real test. A deeper thought makes me feel this world is so cold. The risk for this problem is little, the bigger part is about sacrificing the traveling time to save, a stranger. And... if this is really a way to save him... P.S. Finally the problem turned out to be caused by an unconfirmed flight ticket. A guy traveling from African to GuangZhou with 4 connecting flights from different airlines. I do imagine people treat him worse than normal because he is black, but the whole story is the kind which a normal person will not encounter...
