Kill House.
You haven't robbed a casino, you've stolen a casino.
Or, one better. Kill House and install Yes Man.
You didn't just steal a casino, you stole the Las Vegas strip. Robbing casinos is small time.
Besides, I've already robbed them all of around 10k caps each
And I make a pretty good living robbing vendors.
"I'd like to buy your broken down Ballistic Fist and those good-condition brass knuckles."
duct tape sounds "I'd like to sell you this very good condition Ballistic Fist."
At this point, I've probably got enough caps to swim in ... In fact, I might just do that. Drop them 1 by 1 into a bathtub.
