The ATM calculates the exchange rate of all the different silver items you stole from the Silver Siren. With the x2 multiplier, it comes out to 186 TRUE CASH! You quickly stash it in your wallet, bringing your total up to 555 TC. Sweet! At this rate you might not need the help of a bunch of mysterious wealthy deer after all.
Just kidding. You're on a Big Bucks Quest and you'll be damned if you don't finish it one way or another.
