Did you know that Dean Martin owned 10% interest in the Riviera Hotel and Casino? From 1969 to 1972, Dean Martin worked and at times lived in the Riviera. He even had his own lounge called Dino's Den.
-Dean had a terrible fear of elevators, so his personal suite was located on the second floor of the Riviera. He could walk up and down without use of the elevator.
-Martin was known to meet and greet with high rollers on the gaming floor. The casino host would let him know when they had a big whale on the gaming floor. Dean would hang out and take pictures with them.
-One night a casino host brought some players into Dino's Dean to meet Dean. Martin was hanging out with Frank Sinatra that night. It's rumored that the following happened. Dean offered to take a photo with them and Frank was seated in the background. When the camera flashed, Sinatra erupted in anger because he thought they were trying to take a picture of him. Dean turned around and told Frank to calm down because no one want a picture of his ugly mug.
-Sinatra never once came to see Dean Martin perform at the Riviera.
