I just got back from the Quinalt Casino/Resort in OceanShores and while playing BlackJack I was of course halfway listening to the chatter on the nearby security officers radio, and heard a call for a "Code 5". I questioned the guard and he pointed to 5 guards escorting a lady dealer to the vault. "You'r witness to a code 5 right there," he pointed. Is this a standard code for org's that deal with securing large movements of cash?
