Because they’re so afraid they will be called greedy, they wouldn’t take it if it were forced upon them. Chinese have this neurotic shit they do where at a kid’s birthday, they give them money as a present. If the kid takes the money, they get bitched at for somehow being greedy, and then their parents get shit talked to them for raising such a greedy child.
scenario 1:
Asshole: Here, Chen, here’s some money for candy and fireworks. Happy birthday!
Chen: takes envelope while bowing Thank y-
Asshole: slaps Chen AIYAAAA! What a GREEDY brat!!
Later, on phone or in marketplace:
Asshole: Your child is fuckin’ spoiled rotten! And so GREEDY. I thought you were good people, but apparently you’re just money-grubbing scum. You can be sure everyone will hear of this!
Okay…so maybe Chen should just appear to reluctantly take the money? Here’s what happens:
Chen: No thanks. This party is enough.
Asshole: Oh come on! let me show how much I adore you with a few yuan.
Chen: No, I’d feel bad if I took your money.
Asshole: So humble. Don’t worry, our stand in the market is doing really well. We won’t miss it.
Chen: All right. Th-
Asshole: AIYAAA! slaps Chen Has anyone ever SEEN a child so greedy?! Snatching like a monkey! How can you even LOOK at people?!
The thing to do is to NOT take the money you’re offered…they give the money to your parents to give to you later…but they try like a motherfucker to bully your ass into taking it at the party just so they can talk shit about you and your family if you do. That shit’s bound to fuck people up. No samaritan law may play a part of it, but I’m sure the major factor is they’ve been conditioned by upbringings that punish acting on human nature which results in them acting…well, contrary to human nature and devoid of empathy, aside from a few rare cases.
