Kev here in NY and i'm sure at the otb you were at you can go right to the manager and tell them what machine,the total of the voucher and they could go right into the computer and stop payment of that voucher.A guy i do business with once hit for 5 grand and lost his ticket and informed the manager.Told him what track he hit.1 otb bum tried to cash it and they caught her and barred he from the otb (like that's such a big deal)but he got paid because they had the printout.Sorry to hear about that though Kev.
