Many, many years ago I received a surprise medical bill after my wife and I went to see a Canberra fertility specialist I won't name given his fraudulent actions.
This doctor was clearly very well-off, had his current-model BMW and wonderfully appointed offices. On the way out of our one visit to him (his advice was so useless we never went back - and I was furious at his billing), we learned how he could afford all of this.
His receptionist issued an invoice based upon his instructions, charging each of us for a consultation! We saw him together, and this fraud billed for two consultations!!!
I made quite a bit of noise, but my wife persuaded me to just 'move on' - and not to report his misdeed to Medicare (yes, he was billing Medicare i.e. the taxpayer twice). I appreciate most of her advice, but still regret that I listened to her that time.
"I saw both of you, and spoke with both of you. That constitutes two consultations." GRR!
