Amber's sis Crystal is a pretty rough-looking character. If she says it's two bucks for a shower, Amber better pay up. But whoa, Amber will shower away forty bucks between quitting her job and when she buses off to the Tucson flophouse. That's a day's pay. Then she's got that one pair of khakis to launder.
Did she ever say why she had to wait until October to leave? Is she waiting for that Wishadoo! stash to grow? Why not take her bus ticket, unspendable ten-dollar debit card, put mom's groceries in a doggy bag, and take off now? Next week, she could be back in Dave's loving bony arms. Or maybe not.
