How to gift shitty people during christmass

If they asking for money, give them but instead of a bill give them a cent. For example they're asking for a 300 instead of giving them a 300$ bills give them a 300$ cents put it into a jar and tell them that it's your savings so it might be more than 300 by saying they'll become curious and would actually count all the cent only for it to be exactly 300$

Wrap a big ass box to make it look like you got them something expensive only for it to be a piece of coal or if they cheated on you, you can print out the evidence and out those inside the box( ° ʖ °)
