He thinks it is "fun" to antagonize people. I will suggest that being a constant pain in the ass at the tables will get you one step closer to the door.
Suggest whatever you want, but your statement is untrue. I have found that being loud, obnoxious and mean gets you plenty of mileage in the casinos. The stereotypical counter is quiet and reserved and that is just what the pit is looking for (other than the way you play, of course) when trying to determine if you are counting cards. If the floorman has to come over every five minutes to tell you to stop swearing then, chances are, he cannot concentrate on your play as well. And think about it, how many unpleasant ploppies have you been around in the casinos? Probably a lot, I know I have. So you blend right in with all the other groucers and grumblers. I've only been backed off when using my 'nice guy' routine; never when playing the unlikable bastard.
And, for the record, antagonizing people is fun. That's yet another good reason to do it.
