Their "cash count" doesn't add up.
First, Steele tells Laura that if she had to give more than a dollar for a hot shower, she'd be out of luck.
Then they take a cab to the racetrack, even though a dollar should hardly be enough for two bus tickets. Did Candy give them some cash? Probably not, but who knows?
Later, when they're looking for Harrigan, they only have enough money for one cot, which means no more than a dollar is left in the morning.
What did they hock to get to the racetrack again, it's $5 per person? And how much did they get for Laura's necklace? $10 to pay for two admission tickets on the first days and $2-3 more to pay for one cot? A necklace isn't worth hocking for $13.
