The only problem is...slot machines DO eventually payoff with persistence...and that generally takes you standing there putting money into it constantly. With another person you cannot constantly attend/pester them...that will have the opposite affect.
Not only that...but in my situation I could pay constant attention to my LDH and he'd do nothing but eat it up, not giving back what I need until I finally break down and say something or get angry. Also, if I'm playing a slot machine...I go in knowing I may get absolutely no return on my money, there's no emotional investment in it for me...not the same when dealing with another person.
