Had a well known deaf actress on a flight from LAX to SYD a few years ago who decided that First looked much nicer that than the JCL seat she had been allocated, so she reseated herself!
When it was noticed that she had done this the CSM politely went up and explained to her that she could not do this! She played dumb and pulled the "I'm deaf and can't understand you card".
The CSM calmly walked away and wrote it all down on piece of paper for her. At this she went "spare" yelling and ranting! "Don't you know who I am?" "How dare you insult me by writing things down, Im deaf not stupid!" etc!! The CSM simply wrote on the same piece of paper "police will meet you in Sydney!"
She moved faster than a rat up a drainpipe!! Would have been the most publicity she has had in a while!!
