Why I don't give to beggars on the subway

(in addition to the fact that it's illegal to beg on the trains)

From Overheard in New York:

Subway beggar to the people on train : Yo, my daughter just died and I don't have any money to bury her... (recognizes someone on the train) Yo!
Man on the train: Hey! How's the wife?
Subway beggar: Oh, she good, she good. She be working too! She working on the 4 line!
