Roger is correct. Las Vegas casinos have gotten tougher to buy from. Four Queens and Binions appear to be the strictest! Last time at Palms, I was able to buy just 5 chips from a table, no picking by dealer, pit boss in an amicable mood that moment. This was before the new chips appeared and so of course I got nothing particularly exciting. I then bought a stack of 20 at the craps table. I was able to sneak off with them after my cell phone "rang." Helpful to have a cellular in your pocket and make believe it's on vibrate and someone is calling. That reminds me: next time I try the Palms, I'll whip out the phone and say, "Hey, Roger Herman, duuuude!! Wassup?" (Might as well drag Roger into this scheme . . . )
