Casino Letter Of the Day–Harrah's Laughlin

Today we continue the series of letters from Harrah's casinos.

Today’s featured letters comes from the Harrah's in Laughlin Nevada.

Today's rejection letter is also a first due to 'security reasons'!! I cannot fathom a reason how this could be the case. They can give decks away for free or sell them at the casino, but can't mail them out due to security reasons??

Any ideas, friends?
