Bought in for roughly $5000. Cashed out $9100 at the cage. Played unrated at a Vegas store on the strip. Asked for players card, I said I had none. They said you need one to cash this amount out. I said I don't want to give up my SS for fear of identity theft. They insisted I could not cash out this amount without players card (thus giving up all ID & SS). I eventually gave in.

Do I need to give up this information when cashing out amounts near $10K at vegas joints? Or should I have grabbed my chips back, go back slowly and break them down at other table games, and chip them out over time. [Problem was I had 1 day left in Vegas and it'll be a while before I return]

What were my optimal choices? Were they just BS'ing me? Could I have cashed out if I stayed firm and said I'm not giving up ID?
