Food that one wonders why / how someone could create that. Machines that don't pay - oh maybe once a year so they can claim they do. Read some books on how Vegas changed and those changes created more customers.
So tight that they have not connected that they make more money by being generous - a lesson learned in Vegas decades ago. Instead, they say that the machines are not tight - you're just on a losing streak. I have no idea why they don't think that just maybe someone is right. People have been saying they need professional management / training for years. If you fall victim to any of those positive reviews, you will go and walk out wondering why you did that.
If you see a positive review, I'll bet you and win that it was written by an employee or someone paid to write something positive. This place was bad 11 years ago and nothing has changed.
