At my last trip to Potowatomi in Milwaukee last month (it happened to be my birthday) Security made EVERYONE entering the casino proper hand over their drivers license to be scanned. No entry otherwise. I asked why, the guard glumly replied, "We card everyone under 40. And happy birthday!" Uh-huh... I've been going there for many years, and this was a first. I've never been to a casino elsewhere in the US where you had to hand over your license to be scanned for admittance. Aside from privacy issues, it created a massive line (on a slow night). I don't know how they'll sustain this practice. Has anyone encountered this practice at other casinos?
