Jack - I suggested that many times- politely phrased, of course. Something like: Next time you go on vacation why not go to Arizona or Florida and get a check-out in a C180 or a 310 instead of buying another $15,000 watch or treating yourself to all that expensive "entertainment" on overnights? You might just save your job or even your life some day...
Zero interest. They thought I was out of my mind.
