wors service ever

My self and my partner go there regularly and from what I know its realy gone from good to bad and worse . Our expectation from an international entertainment company were people spend Millions means services should be of the highest standards but its not . One gets attitude from bar staff they take there own time acknowledging you and that you need service and when you ask them about it they automatically give you the cold shoulder. What took my complaint to the edge is the fact that staff argue infront of the customers and when u ask them to stop they like little kids continue argueing, is it just me over seeing things ? Total lack of service and management . I hope someone takes this matters seriously
