wow, Sidney really took advantage of Billy at the end...
I know Sidney was having money troubles but he really took advantage of Billy's weak spot: his gambling addiction. He was just standing there while Gloria was breaking up with Billy and he didn't even offer to look for another solution.
Worst part is, after the match in the hotel, he says "listen to the woman". How's that for rubbing it in.
