because if a theft issue wanted to make sure they were yours.
You'd probably get a more accurate answer if you asked an employee there at the cashier cage. But I know I've had to show ID when cashing out a voucher for a substantial amount and I asked then and was given the answer that they were making sure my info i.e. address etc. Was up to date. Go figure why a cashier would do this especially since I'm at the players club every time I'm there, you'd think if there was question of being "up to date" they'd be the ones checking.
