Kirby's Ace
Getting back to Brandywine Raceway have individual windows for each denomination of bet W-P-S. In those days they didn't have the ability to cancel tickets so if a teller punched out the wrong ticket, he'd be on the hook for the money if he couldn't get it sold before the race. I knew the $50 seller there and one time he got stuck eating (2) $50 win tickets because he punched out the wrong number. Unfortunately for him, the horse didn't win.
