Scumbag Poker Staking

[Gata Kamsky]

What do you tell a person whom you staked for some money for 50% of the profit at a session, then lose it all but put up some of their money and win back your money and then say they don't want to pay you back because they put up their money in that session too? Eventually they lost it all which I was happy to see even though I lost my money but I really want to let them have it as it's been a while and they deserve to be put in their place?
