Backroom and garage poker and craps with acquaintances and "friends of friends" can sometimes be a fast road to broke, too.
Not uncommon for two to play as partners unknown to other players.
Then there's marked cards, and assorted crooked crap shooting devices.
Still got dad's little catalogue of nothing but crooked gambling products -- everything from pre-marked decks of cards in all major brands and devices and dyes to mark 'clean' decks while in play, loaded and shaved dice and electromagnets, punch boards with the winner keys, ...you name it... The seller played it off as a catalogue of "Magic Tricks".
I watched dad clean them out time after time and take their whole paycheck then they thanked him for loaning them $20 till next payday.
