stealing my money

[lef1000]

long story short
i play in this game every other day
and usualy make money from it
its a small stakes game where typical buy in is $20 but by the end of the night there is usaly $200 total.

during cash out my "friends" basicaly screwed me out of half my winnings and told me that they dont owe me [censored] and drove away.

whats my line here? obc im not playing with them again but what do i do in this situation?
