Two things:
To your first point you totally get what the character is about!
To the second Richard Rawlings is a regular at your pool hall/bar? Sounds a lot like him:grin-square:
The guy reminds me of Jamie Kennedy in Malibu's Most Wanted

I've not seen our guy pull off any big money yet but I'm waiting. I feel like Eddie watching Vincent for the first time thinking...this guy can't be real.
One other thing my guy does is constantly checks his big watch...when he does, he snaps his arm/wrist straight forward and then slowly bends it as he looks down at the time...Freaking brilliant.
I will try and snap a pic of him next time and try and blue his face so you can see.
