Just before I got my WEST-PAC orders for Nam, McDonalds came out with the Big-Mac. For 13 months while in-country all I thought about was eating a Big Mac and drinking anything that was cold that had ice cubes in it.
When I got on that "Freedom Bird" and when that Continental Airlines flight landed at MCAS El TORO as soon as I cleared customs and got my orders the first thing I did was stop at a McDonalds and ate two Big Macs and two large cokes with ice.
Today I might eat at McDonalds once every 18 months. The only fast food I eat today is a Double-Double at "In n Out" and once or twice a year Del-Taco.
