In the Fog - Richard Harding Davis - Bog

The Grill is the club most difficult of access in the world. To be placed on its rolls distinguishes the new member as greatly as though he had received a vacant Garter or had been caricatured in "Vanity Fair." Men who belong to the Grill Club never mention that fact. If you were to ask one of them which clubs he frequents, he will name all save that particular one. He is afraid if he told you he belonged to the Grill, that it would sound like boasting.
