Careful when you play in the high limit slot area. We are diamond status members and spend thousands in the high limit area playing slots from $25 to $100. On our last trip August 20, 2011 we observed that a 7 star member asked an employee to shut down a $100 machine so she can play it later. I had 1000's in that machine and was going to try myself again. However, the machine was now "reserved" for that person, and therefore the gaming odds were changed for everyone else. This is not illegal but highly questionable conduct. I requested to speak to a manager because. Took forever but the floor manager showed up because I had repeatably asked and insisted to see a manager. The floor manager endorsed the employees behavior and told me that sometimes machines are reserved for 7 star players when they go to the restroom or dinner. In this case however the lady was 10 feet from us playing other machines. The good odds on that machine were waiting for her and were not available for the rest of you people. MAKE SURE YOU GET FAIR ODDS AND ARE NOT CHEATED OUT OF YOUR CHANCE TO WIN IN FAVOR OF ONE OF THEIR 7 - STAR MEMBERS.
