Emperors Palace mng dont even care about staff

I have had many problems with bad attitude from staff on the gaming floor and on Tuesday 6 October 2015 I finally realised why. I have played tables numerous times now when the same man joins the table and he swears and insults the dealers ALL the time to such a point that I actually feel extremely sorry for the dealer. I kept my mouth shut but on Tues I could no longer take it. I told this man to stop the abuse as the lady is also a human being with feelings and he has no right to talk to anyone like that. He started insulting my husband who was not even there and he does not know him and he insulted me and swore at me. Security came and like usual only stood there did nothing about this man. Management came and also gave him a warming. ALL staff at the tables are aware of what this man does and still management refuses to ban him because all this place cares about is the money. He started with death threats and still they did not throw him out. How can any business allow someone to abuse their staff and other guests or clients like that??? This man has such a bad reputation that other guests stood there and said they also hear him doing this over and over again.
