Money laundering eh? Read Barry Meadows book "Blackjack Autumn", a tour of every casino in NV. with a bj game, and he was scamming Canadian dollars in Reno, a popular destination for Great White Northerners. Meadows is a pro gambler and scored $15,000 CN at a good price in LV and was putting it in play in Reno casinos. The ready familiarity of Reno with CN dollars and daily changes in the official exchange rate made it a good opportunity, except the Reno casinos were on the lookout for this dodge. They don't mind suckers from Medicine Hat but they don't want to do business with operators from L.A. Great Clouseu action between paranoid pit critters and a paranoid card counter. Perhaps the "money laundering" mumble mouth at the Sand Reg was just a grouchy drone thinking something was going on but just couldn't figure out what. Durn hobbyists.
