Went to casino last year and got a member card. Visited again this May and forget my card so went to the desk and handed them my Canadian driving license at the same time requesting another card. They said I needed a passport as I was a "foreign national". I asked why I needed a passport just to get another card? Policy. I asked to speak to a manager. I have never been asked to produce a passport in any of the ten or so casinos that I frequent in Oregon, Washington, California. I was told it was policy and that I could not go into the casino without producing my passport. They were extremely unpleasant and I was totally caught off guard. Some Canadian friends went later that evening. One of them signed up for the first time to get a member card and was not asked to produce her passport. Has anyone else ever been asked to produce their passport in a casino?
