OMG!! EWL, if I didn't know better I would say you had dealt with an acquaintance of mine. Bi-polar 1 (hi-tech jargon for nutty as a fruit cake), autistic, & has OCD (obsessive-compulsive disorder). A walking disaster! During one of her major manic episodes she apparently got on a one way business class flight from Perth to Canberra. Ended up there with no money, no food & nowhere to go. Attempted suicide & ended up in hospital. So obviously you are not the first person to sell a ticket to someone like this.

P.S. Please tell me you're NOT in Perth!!
