The Live and Let Die novel by Ian Fleming was published in 1954. In that, Bond stays at the St. Regis; he tries to make himself seem more "American" to throw off the enemy.

"He was reminded to ask for the 'check' rather than the 'bill,' to say 'cab' instead of 'taxi' and to avoid words of more than two syllables."
