the final truth

I was wondering what happened in that diner during the whole movie, but finally, what you got is that a guy pissed in his pants. And why is that so hard for the kid to accept that a adult pisses in his pants, when he is having a gun point at his head, when he knows he is going to die, and he is dead too.
I really don't like this part of the history.
But the part with Forest Whitaker is not bad, and I would also like to mention Jennifer Hudson's performance, she fit in her character so well, although there are just about 10 minutes of her appearance total. No wonder she won an Oscar for her first movie.
