Charlie Lombardo, cited in the article, is one of the most experienced casino slot machine operators there is. He was VP of slot Operations at Bally's Las Vegas for many years. I'm glad I was able to introduce him to my son at last year's G2E show. Charlie's counterpart in Reno, Buddy Frank, stopped by where my son now works and introduced himself. Some of the best experience in the business. You can't learn what they know from textbooks.
