Sometimes,poker players are thrown out from poker rooms due to bad behavior.To prevent this,a poker player should behave properly while playing. The following points should be kept in mind :-

Do not ever try to cheat the house. This is the biggest sin in a casino or cardroom.
If you ever try to cheat a Las Vegas casino and get caught,you are immediately handed over to the Police and you get banned for life. In your local cardrooms too,if you get caught cheating,you are immediately driven out and may face other consequences.
Do not cheat or steal from other players.If the dealer incorrectly gives money to you and you refuse to give it back, knowing fully well that you did not win it, then you can be asked to leave. If you collude with another player with the intent to cheat others,then both of you may be kicked out.

Do not fight with other players. If you ever start a fight,you won't be allowed in the room. You may even be handed over to the Police.

You must adhere to the rules of the casino or you may be driven out.Things like talking on your cellphone while at the table or throwing the cards at the dealer, are not tolerated. If somebody is intoxicated and engages in unruly behavior, he is more likely to be asked to leave.

So if you don't want to be thrown out of a poker room,please behave yourself,play peacefully and obey the rules of the house.
