Nice find!

I thought Borland's maitre D job at the Dunes was at the dome-shaped (seafood ?) restaurant. I don't recall the exact name (maybe Dome of the Sea or something like that?).

The only time I met Borland (and Starr Warrick) was at their apartment. He never mentioned his Dunes career -- keeping his "The Gambler" chips & LV poster activities separate, I guess.
