"I lost $20 at Disneyland on the Monorail, back when I was eleven," I said. And she handed me a sawbuck, just like that.
How do they stay in business? Volume!
EDIT: This post contains a factual error. A sawbuck is a ten dollar bill, not a twenty, so, she actually gave me a double-sawbuck. Thanks to Cobra Commander prester_scott for pointing this out. I strive to keep my journal free of all inaccuracy, of course.
