Should start having the security check in on people booing at games:
Security - "Mate, are your boo's directed at Latrell Mitchell?"
Fan - "Ummmm, yes....he um, kneed a bloke in the head....."
Security - "I'd ask that you refrain from booing Latrell Mitchell..."
Fan - "Can I boo Munster instead?"
Security - "Yes...."
*Fan proceeds to boo at Munster*
Security - "Are you some sort of racist? I told you not to boo Latrell Mitchell..."
Fan - "I...I didnt...I just directed my boo toward the field, Munster scored a try and this is all a misunderstanding.....I said Boo-urrnnnns"
Security - ".......just don't boo. Sit there and watch the game. He could hear you and take it to heart, do you want that on your conscience?"
Fan - "I guess not...."
Security - "Enjoy your game day experience sir."
