Okay. Hmm. So . . . .did these other guys know that Bert was trading on their names?

Were there other guys, or was Bert counting on the provincial nature of most people, and took a bet they’d never been to these other places?

From Historic Restaurants of Washington:

Olmsted claimed to own oyster beds off Chincoteague Island in the Chesapeake that were washed over by ocean waters and thus acquired a pleasant salty taste. Using these select oysters, Chef René Roux prepared Baked Oysters Casino according to a “300-year-old family recipe.” The dish remained a major draw for the restaurant for many years until the Olmsted Grill closed in 1962.
