He wouldn't. Because Mickey is the type of person who only wants to think about him as being a winner, and he gets angry at someone being a much better/more successful gambler than he is....esp. someone who doesn't let it consume his entire life.
$1500 or $2500, it wouldn't matter to a nobody like him. He's just an angry, lonely, old man with a vastly unfulfilled life....one who's spent years crawling around on gaming forums as a feckless human being.
Can you just IMAGINE what would happen to him if this forum shut down? I see it as an entertaining event: he sees it as horrifying. And I would love every minute that I contemplated his suffering over it.
