Security attitude

I entered the Casino complex to attend to a birthday function with friends at the Ten Pin Bowling. I carry a licensed firearm which is concealed with only the bottom part of the holster showing below the sweater I was wearing. The guard at the door advised that I should put the firearm in my vehicle which I advised I am prohibited by law to do. I entered the bowling alley and started playing with my firearm still concealed and on my person. After some time your Security Supervisor, Herbert Mothupi arrived with the guard and 2 x armed Tactical Response guards and advised me that I must leave the premises. I advised him and showed him my license. He said that the Casino rules state that I am not allowed to carry a firearm and that if I don't leave he will call the SAPS. I then called the Duty Manager, Patrick, who arrived but said that he is not responsible as it is a safety issue. I then enquired if there is a safe oj site where I can store my firearm and was advised that there is not. Herbert then again said that I must cooperate or he will call the SAPS. I then left as I don't want to cause a scene where people are enjoying a birthday. I was treated with utter disregard and disrespect and I am not happy with this. When asking to speak with Herbert's manager, he advised me that he is the manager. Poor attitude.
