The MGM in Vegas should have had Pai Gow just to see if the Asian community would have passed the lions to get to it
I would have thought in Macau, the Wynn and Venetian would have kept a close eye on their staff. You could understand the less well known "local" places having some issues but at these multi-billion $ corps, I would have thought they'd be very strict on how customers were treated.
Reading some reviews of people who have stayed at the Venetian it sounds like it opened too early - lots of complaints about bad service and the staff not knowing their jobs properly, stuff not ready, etc etc.
