Somebody slap me "(up the side of the head!)".I have been playing long enough to know better but recently at the Silverado Bar at the South Point probably due to to too many soothing brown beverages I went to the restroom and tipped my chair against the VP machine and covered the screen with Two Napkins.When I returned there were two guys sitting either side of the VP machine and one of them tapping the keys.There was one bartender and only one other player 3 seats down from my position and all other bar tops vacant. I was astonished and asked the bigger guy what the heck he was doing playing my machine that still had the napkins over it and the seat tilted inwards.He told me he was "just hitting the keys to understand the game.I told him I thought he was trying to steal the money I had in there.He became very aggressive so I called the Bartender who glanced over and carried on doing his work.I sat down to play,(the money was still on the machine) with one of them each side of me and they finally left after a few minutes growling and staring at me on the way out.Needless to say it was a bit nerve racking wondering if an altercation was about to begin.At my age I would have no chance.Seems "Bizarro"!so everybody remember don't have the blind faith I do and take your money out even if somebody says they will watch it for you and it will save any possible problems arising.
