A couple years back, I was at the Phoenix airport bar.  It was empty except for one heavy-set, gray bearded, grizzled guy who looked like he just rode his donkey into town after a long day of panning for silver in them thar hills. 

He ordered a Jack Daniels straight up, and that's when I overheard the young guy with the earring behind the bar asking him if he had ID.  At first the old sea captain just laughed.  But the guy with the twinkle in his ear asked again.  At this point it became apparent that he was serious.  Dan Haggerty's dad fired back, "You've got to be kidding me, son."  The bartender replied, "New policy.  Everyone has to show their ID."  Then I watched Burl Ives reluctantly reach into his dungarees and pull out his military identification card from World War II.
