Blown away by some pilots on this thread.
My son has aspergers (now called social-pragmatic disorder). He'll never follow in my footsteps and fly mil or 121. He will drive vans. Giving is about helping the less advantaged vs some daily adjusted monetary value or long term net worth. Worship your stuff I guess. Maybe it comes down to how you value yourself.
I tip $5. SHOCKER! Over the holidays I tip more. Including minority folks cleaning up my table at the restaurants. Not because I have it, but because they need it more then I.
If this resonates with one young pilot then I'm glad I got on a soapbox.
