The casinos don't "target" people with low income....those people WALK in!
I once reported a casino - name withhold so I won't get sued. I went to several machines, and as the machines started paying off, DARN IT, the machine would jam up....after it happened in 5 machines, I left and reported them. Never heard IF anything happened though. I don't like hearing the casinos are able to get out of paying. If the gambler did something to the machine, then yes, they shouldn't have to pay. But if something's wrong with the machine, that's the CASINO's problem!
