I was processed out of the Navy there in Jan 1972. Stayed in a transit barracks for a week or so while waiting to be discharged. When I first arrived I kind of just hung around base a day or so until I joined a few guys who were cool and we went downtown SF looking for hippie chicks. But one evening while staying on base I wandered into the barracks lounge to watch TV or something. And to my surprise I saw a beer dispensing machine in there. I couldn't believe it. A beer machine in a barracks? Upon closer examination I saw that the only beer it had was SCHLITZ. But the price was affordable, 35 cents. I dropped the required amount in the slot, pushed the large square button with the picture of SCHLITZ on it and presto! A cold can of beer rolled into the lower tray. FAR OUT!! I turned on the TV, nobody was in the lounge, and watched whatever SF offered that evening. Enjoyed a few more of those machine beers and then crashed for the night.
I tell you one more thing. It turned out that beer wasn't the only product you could buy in that transit barracks at TI.
Those were the days my friend.
